What can i do for insomnia from a diet pill?

Try: Sleep hygiene. Avoid laying bed in the day time, no naps, turn off external stimulators, excercise 3-4 hours before bedtime, go to bed at regular time, try hot shower before bed time and take diet pill early in the morning. If symptoms persist after a week of diet pill and implementation of sleep hygiene may discuss alternative therapy for weight loss with your doctor.

Suggestions...: I suggest that you reduce your exposure to computer screens and television before bed. Read and turn on some quiet music or a fan (or get a white-noise app on your phone). Try some herbal tea and make sure the room is cool and comfortable when you try to sleep. If that doesn't help soon, talk to your prescribing doctor.

Diet pills...: are stimulants as you are now painfully aware. My advice, stop taking the diet pills. The effect should wear off and you will have a better nights sleep tomorrow. I would advise against trying to take another medication tonight to try to sleep. Relax, take deep breaths, close your eyes in a dark room... Good luck.
