The short answer: Chronic insomnia is almost always a symptom of an underlying root cause — not a primary diagnosis to medicate. Most sleep problems fall into one of three patterns: can’t fall asleep, can’t stay asleep, or sleep that doesn’t restore. The underlying drivers are usually cortisol dysregulation, hormonal imbalance (especially perimenopause and andropause), blood sugar dysregulation, magnesium deficiency, thyroid dysfunction, undiagnosed sleep apnea, chronic infection, or mitochondrial dysfunction. At InfusaLounge in Allen, TX, the approach starts with comprehensive labs to identify which root cause is driving your case, followed by a targeted protocol that may include sleep peptides, hormone optimization, nutrient and mineral support, NAD+ IV therapy, and lifestyle adjustments — not long-term drugs.
It is 3:14 in the morning. You have been awake since 1:47. The ceiling is doing nothing interesting. You did not have coffee after noon, you turned the screens off at nine, you took the magnesium, you tried the meditation app — and yet here you are, mind racing, body wired, watching another night dissolve. You already know what tomorrow will feel like.
If this is a story you have lived for months or years, you have probably been told the same things by every well-meaning doctor and friend: it’s stress, drink less wine, try melatonin, maybe take a sleep aid. None of which is actually wrong, and none of which actually fixes anything. The truth most people are not told is that chronic insomnia is almost always a symptom of something else — and the something else is identifiable, measurable, and treatable. Here’s what that workup looks like and what real treatment involves.
The Three Sleep Patterns We See Most
Before we talk about causes, it helps to name your specific sleep pattern. Most sleep problems fall into three patterns: can’t fall asleep, can’t stay asleep, or sleep that does not restore. Each pattern points to different root causes and responds to different interventions.
Can’t fall asleep. Lying in bed for an hour or more before sleep finally comes — mind racing, body tense, often hot. Usually associated with stress, anxiety, or evening cortisol that should have dropped but did not.
Can’t stay asleep. You fall asleep fine but wake at 2 or 3 AM and cannot get back. Sometimes accompanied by night sweats, anxiety, racing thoughts, or just being mysteriously wide awake. Very common in perimenopause and andropause, but also seen in chronic stress and blood sugar dysregulation.
Sleep that does not restore. You sleep 7 or 8 hours and wake up feeling like you slept 3. Non-restorative sleep is one of the most missed sleep problems because the hours look right on a sleep tracker. The architecture of your sleep — particularly deep sleep and REM — is disrupted in ways the tracker cannot detect.
Most patients fit one of these patterns, sometimes two, occasionally all three. Knowing which one is yours is the first step toward fixing it.
What Is Actually Going Wrong
With your pattern identified, here are the root causes we investigate. The drivers of chronic insomnia are usually one or more of these, each requiring identification rather than a sleep aid.
Cortisol dysregulation is the most common pattern in stressed-out professionals. Cortisol should peak in the early morning and bottom out at bedtime. In many adults with sleep issues, that pattern is inverted or flattened — high at night, flat in the morning. Stress, chronic illness, and burnout all distort the cortisol curve over time.
Sex hormone imbalance accounts for a significant percentage of sleep complaints in patients over 40. Low progesterone in women and low testosterone in men both correlate strongly with sleep disruption. Perimenopausal women in particular often have sleep that disintegrates years before their periods stop. The North American Menopause Society reports that 40 to 60% of perimenopausal women experience significant sleep disruption.
Blood sugar dysregulation is the answer for many 2-to-3-AM wakers. Blood sugar drops too low overnight, the body releases adrenaline and cortisol to correct it, and that adrenaline release wakes them up. The wakeup isn’t psychological — it’s biochemical.
Magnesium and mineral deficiency is almost universal. Magnesium is the calming mineral, and most adults are mildly to moderately deficient. Inadequate magnesium directly affects both sleep onset and sleep maintenance.
Thyroid dysfunction affects sleep in both directions — hyperthyroidism makes you wired and hypothyroidism makes you exhausted but restless. Often missed when only TSH is tested. A full panel is always indicated when sleep is the chief complaint.
Undiagnosed sleep apnea deserves its own mention because it is frequently missed in women, in younger adults, and in patients who do not snore loudly. The American Academy of Sleep Medicine estimates undiagnosed sleep apnea affects roughly 80% of those with the condition.
Chronic infection or inflammation — long COVID, EBV reactivation, Lyme, mold exposure, and other persistent infections — all disrupt sleep architecture.
Mitochondrial dysfunction is the last common culprit. Your brain needs cellular energy to produce the neurotransmitters that govern sleep. NAD+ deficiency interferes with this directly — see our NAD+ article for the bioavailability rationale.
The InfusaLounge Sleep Workup
When sleep is the chief complaint, guessing is a waste of your time and money. Comprehensive labs identify which of the above causes is driving your specific case. The testing typically includes:
- Hormone panel with cortisol rhythm (4-point salivary or urine)
- Full thyroid panel: TSH, Free T3, Free T4, Reverse T3, and thyroid antibodies
- Fasting insulin with A1C and fasting glucose
- Magnesium RBC and other key minerals
- Inflammation markers (hs-CRP, homocysteine)
- Vitamin D, B12, and ferritin
- Sleep apnea screening when indicated — modern home sleep tests have made this much more accessible
Dr. Gee interprets results in the context of your specific sleep pattern. The same lab values mean different things for a “can’t fall asleep” patient versus a “can’t stay asleep” patient.
The Therapeutic Tools We Use
Once the workup is complete, treatment typically combines several tools used together. The right combination depends on your specific root causes — this isn’t a one-size protocol.
The sleep peptide stack (DSIP plus Selank) is one of the most-used protocols when peptides are appropriate and available. Delta Sleep-Inducing Peptide (DSIP) has been researched for its role in slow-wave sleep, and Selank has been studied for stress and anxiety regulation. The clinical evidence base for both is still developing, and neither is an FDA-approved medication; whether either is appropriate for you is a clinical decision made at your consultation. As with all peptide therapies, availability depends on current 503A and 503B compounding pathways — see our peptide therapy article for the regulatory context.
Hormone optimization (BHRT) is the answer for many midlife patients. For perimenopausal women, progesterone is one option we consider for middle-of-the-night waking; for men with low testosterone, optimizing hormone levels may support sleep quality and daytime energy. Whether hormone therapy is appropriate — and in which form — is an individualized clinical decision based on your labs and history. See our perimenopause and menopause article for the full BHRT picture in women, and our hormone optimization page for men.
Magnesium and mineral support is foundational. Targeted oral supplementation, sometimes combined with IV magnesium for severe deficiency.
NAD+ IV therapy helps patients whose sleep issues correlate with chronic fatigue and mitochondrial dysfunction, supporting the cellular energy needed for healthy sleep regulation.
Cortisol rhythm support for patients with disrupted curves — adaptogenic herbs, targeted supplementation, and lifestyle protocols to restore the normal pattern.
Blood sugar stabilization for 2-to-3-AM wakers. Evening protein, strategic carb timing, and sometimes a specific supplement protocol resolves the nocturnal hypoglycemia driving the wakeup.
For patients in burnout patterns, the walk-in wellness stack often runs alongside the sleep protocol — the same cellular support that addresses burnout also supports sleep recovery.
A Typical Treatment Path
Most sleep patients follow a 90-day path. The first week is consultation with Triny Nguyen, FNP-BC and lab orders; basic supplement support may start immediately if appropriate. Weeks 2 to 3 cover results review and treatment plan design, with BHRT initiated if indicated. Weeks 4 to 8 are active treatment — most patients see meaningful improvement within this window. Different tools work on different timelines; hormonal interventions in particular typically take 4 to 8 weeks for full effect.
Weeks 8 to 12 are refinement — dose adjustments based on response, repeat labs as needed, addressing any remaining issues. After that, most patients stabilize on a maintenance protocol.
What We Do Not Do
A few things we will not be doing, and it is worth being explicit about them.
We do not prescribe long-term Ambien, Lunesta, or other Z-drugs (as they are commonly called). They can be useful short-term but do not address root causes and have well-documented dependency and cognitive side effects. We do not recommend high-dose melatonin for most adults — most patients have already tried it, and most have found it either does not work or works briefly and then stops. And we do not dismiss sleep complaints as anxiety. Anxiety can cause poor sleep, but poor sleep also causes anxiety. The arrow runs both directions.
Frequently Asked Questions
Can I do sleep peptides if I am on other medications?
Usually yes. Your medications will be reviewed at consultation.
Will I become dependent on sleep peptides?
That is a question to raise at your consultation. These peptides are used under clinical supervision, often cycled rather than taken continuously, and your provider will review the current evidence and your full medication list before recommending them.
Do I need a sleep study?
Not always, but one may be recommended if there is any indication of sleep apnea. Home sleep tests have made this much more accessible than the old in-lab studies.
How fast does the sleep peptide stack work?
It varies from person to person and depends on the underlying cause. Your provider will set realistic expectations at consultation based on your specific plan.
Can I do this protocol alongside my GLP-1 medication?
Yes. Many of our weight loss patients also do sleep work, since weight loss alone often does not fix sleep issues caused by hormonal or stress factors. See our tirzepatide side effect management article for related considerations.
What if my labs come back “normal” but I still can’t sleep?
This happens often — conventional reference ranges are not the same as optimal ranges, particularly for thyroid and cortisol. Labs are interpreted in the context of your symptoms, not just in isolation. This is one of the main reasons functional medicine workups identify things conventional workups miss.
You Deserve Real Sleep
If you have been struggling with sleep for months or years, the path forward is not another sleep app. It is a real clinical investigation and a personalized protocol that addresses what is actually wrong.
