It seems you are experiencing sleep-maintenance insomnia (difficulty staying asleep) despite medications. Zolpidem mainly helps with sleep initiation, but may not always maintain sleep for the whole night. Since melatonin is giving you side effects, increasing its dose is not advisable.
Some points to consider:
• Avoid alcohol, nicotine, and caffeine (especially after evening).
• Maintain a fixed sleep and wake time, even on weekends.
• Avoid lying in bed awake for long; if you wake up and can’t sleep within 20 minutes, get up, do something relaxing (dim light reading, relaxation exercise), and return to bed when sleepy.
• Ensure your bedroom is dark, cool, and quiet.
• Since you are already doing yoga, meditation, and screen restriction, you are on the right track.
Next Steps
Discuss with your psychiatrist/physician about other options which are more effective for sleep maintenance.
• A proper evaluation for causes of chronic fatigue and insomnia is important—
thyroid function,
vitamin B12,
vitamin D, anemia, sleep apnea, or mood/anxiety disorders should be ruled out.
• Consider Cognitive Behavioral Therapy for Insomnia (CBT-I), which has strong long-term benefits and reduces reliance on medications.
Health Tips
Do not increase medication doses on your own without medical supervision.
• Long-term use of zolpidem carries a risk of dependence and next-day drowsiness, so it should be reviewed regularly.
• If you notice snoring, choking at night, or excessive daytime sleepiness, please get evaluated for sleep apnea.
