How to stay asleep?

I'm over waking up af 3/4AM every other night. I'll be wide awake but fall asleep and almost miss the alarm.  

How can I make myself stay asleep?

I don't know an answer but I'll be watching this thread for info.

Tylenol pm?

Do you drink anything with caffeine after 6 hours before you sleep or watch TV/play games/use your cell less than 2 hours before bed? If so, try eliminating those things - my mother and I had the same issue so when we cut these things out we slept much better. You can read a book or do something that doesn't have a light behind it which can make your brain overwork.

Also, don't drink or eat anything 2 hours before you sleep so you're not processing/needing to pee at 4am.

Failing that, grab some sleeping pills
