what do you do if you are sleepy but you cannot sleep

Latte's! Thank god for starbucks. Also, B12 stips are known to give an energy kick.

Depends, if possible strong coffee, Jolt-cola, energy drinks or anything that contains alot of caffeine works wonders. Any sugary thing could also help, like candy and stuff. If really sleepy, i dont think anything involving violence to one self would help, like hitting certain body parts with blunt objects.

I just find something to do, until the urge for me to fall asleep, trumps the urge for me to stay awake and toss and turn in bed all night. Sometimes I get up and watch tv, get online, read, whatever I can do until I get tired enough to go to sleep.
