What to do if i cannot sleep at night,how to save it?

Eval/sleep hygiene: Have you had a sleep study done to figure out reasons for insomnia? Practice sleep hygiene: keep you room a little on a chilly side, warm shower before bed, bedtime routine: no tv, or anything stimulating, no heavy meals. If you can't fall asleep, get out of bed and do something really boring until you feel sleepy and then go back to bed. Go to bed and wake up at the same time.
