Good old black coffee is pretty effective, if you can drink it of course. Witamin water is also pretty good, it seems to work fine on me. Also you can try taking a nap during the day, that would help you stay up all night[but I guess it's too late for that now]
Get "pumped up" by playing some loud, fast music (rap music, I suggest).
Set your alarm just in case you happen to fall asleep.
Coke, Coffee, and like Destructobot said - take a nap before so you'll feel a bit rested, and your regular sleep pattern will be out of whack.
Crappy tips, hope I helped a tad...gotta write a paper for school?
Stimulants are easily obtained from a doctor but I'm not sure if that would be worth it. Tell them you have ADD or Narcolepsy and you'll get one of these:
- methylphenidate - Fairly short duration, high level of safety. Take 30mg every 4-6 hours and it'll keep you up for however long you need.
- racemic amphetamine - Will make you 'jittery' because of its effects on the physical nervous system.
- dextroamphetamine - Very smooth, very safe. 20mg every 8 hours.
- modafinil - Used by fighter pilots as 'go-pills' to keep them awake for long missions and patrols. Still very new so not enough research has been done. Average safeness
Coffee is good but after it wears off you'll be much more tired than you were before...so make sure you keep drinking a strong cup every 2 hours or so to keep the buzz going.
Micro-naps work awesome. 20 minute nap every 6 hours and you'll be able to stay up for a week!
Methamphetmine off the street if you're that desperate (I don't recommend it nor have I done it) Most doctors will tell you that having a low dose of methamp for a short period of time will not cause any brain damage/dysfunction at all. $10 worth will keep you up for 2 days depending on quality. You won't feel 'speedy' at such a low dose.
Wow that was a long post. I guess you hear about all the ways of staying awake when you work at a hospital
smoke a load of cigarettes (not recommended to smoke with the green stuff it gives the opposite effect
), that will keep you awake, it always does for me, also drink a lot of normal coke, that's has a lot of caffeine in it. and yeah sleeping in the afternoon usually keeps me awake in the evening or night time, like tonight lol
