pop a couple tylenol PMs and about an hour go to bed and pull the covers over your eyes but keep your mouth out to get fresh air..so even if it takes you forever to fall asleep and you happen to open your eyes you will still see nothing but pitch black..
next time get some good coke..with good coke there is no need for anything to comedown with...ive had some great coke and been able to fall asleep right after, of course i was drinkin beers that night but still within 2hours of the last bump i was sleepin
