1) no drinking alcohol
2) no coffee or fizzy drinks.
3) even if you don't sleep,just go to bed at 10.30pm so as to let your body know you're serious. do this after a while,your body and brain,will get the message
4) no exercising before bed.
5) no hot bath/shower..or cold ones either...if you have to shower,do it an hour before.
6) no lights on/tv/or anything that could keep you awake. shut your eyes. let your mind wander,but not too much.
7) drinking milk according to some people or eating cheese helps lol but i seriously doubt that lol
8) drinking herbal teas like chamomile tea etc is supposed to help you feel relaxed enough to sleep.
9) you could try burning scented candles...just remember to put them out before you doze off!
10) set your alarm to wake you at a specific time,so that even if you don't want to get up you'll have. by the end of the day you'll be exhausted and go to bed early.
i'm not a morning person,i'm a night person. sometimes i can do 48 hours without sleep but i try not to. the lastest i've been to bed lately is 4am..and then my body thinks it's ok to do that and then my sleeping pattern gets wrecked...once i would go to bed at 12/2am,get up 4am and be so active..i'd have to force myself to sleep..i'd get up at 6am and still be active but when i woke up at 7.30am when i needed to,i'd be like i hadn't slept for days,so i try not to wreck my sleep pattern...moral of the story is,try not to wreck your sleep.
