DONT DO XANAX'S or VALIUM !! That shit is addictive as fuck. They are psychiatric drugs not sleeping pills.
Go to the herb store and get you something. There are plenty of things there. Melatonin is a good one and their are others.
You sure don't want to be hooked on xanax's or valiums or any of that shit. Just because you can't sleep.
There are other non addictive things that will help you sleep.
