Melatonin supplementation for sleep maintenance insomnia

Low‑dose melatonin (0.5–1 mg, up to 3 mg if needed) is generally safe, non‑addictive, and can be used to shift your circadian phase. Possible side effects include morning grogginess, vivid dreams, headache, or nausea, and it may interact with blood thinners, diabetes or seizure medications. For a sleep‑maintenance problem like waking at 3–4 am, take melatonin 30–60 minutes before your desired bedtime, or try a very low dose (≈0.5 mg) 6–8 hours before the usual 3:30 am awakening to advance your sleep window. In addition to melatonin, follow these sleep‑hygiene steps: * Keep a consistent wake‑time each day, even after a poor night, and aim for 7 hours of consolidated sleep. * Expose yourself to bright natural light for 20–30 minutes soon after waking; avoid bright screens after 9 pm. * Restrict bedtime to match your true sleep need (e.g., if you currently sleep 10:30 pm–3:30 am and 6:00–6:30 am, consider moving bedtime to about 11:00 pm and maintaining a 6:00–6:30 am wake‑time). * If you are awake for more than 15–20 minutes, get out of bed, dim the lights, and engage in a quiet activity until sleepy. * Limit caffeine (no later than noon or, at the latest, 2 pm) and avoid alcohol at night. * Finish dinner at least 3 hours before bedtime. * Use a brief relaxation technique at the time of the awakening (e.g., 4‑7‑8 breathing, body‑scan, or a short “brain‑dump” journal) and avoid looking at the clock or screens. * Consider an evening dose of magnesium glycinate 200–400 mg if tolerated. If awakenings persist beyond 4–6 weeks despite these measures, consider a structured CBT‑I program (e.g., Sleepio or CBT‑I Coach). Seek medical evaluation if you have snoring, reflux, pain, nocturia, untreated sleep apnea, thyroid problems, depression, anxiety, or are taking medications such as beta‑blockers that can affect sleep.
