Cognitive Enhancers

I have read up on it, what would small doses be?
Does it make a difference?

I'm confident in my ability to do well without any chemical help.

I've taken Modafinil for a bit of extra study time when deadlines were looming. It's just turns off the 'tired' feeling.

Sounds good, I might have to give it a try. What would happen if I stayed up for 24 hrs and then crashed? Would I need to sleep it off or would I wake up normal?

It's not a substitute for sleep.
If you stay up for 24 hours to finish some work, you'll need to do some catch-up sleep next day.

I used it to get away with about 4 hours sleep a night while writing the dissertation.

So is it just like better caffine, with less of the bad side effects and more of the good side effects? Could I potentially, if I kept redosing, stay up for a few days?

No, it's not safe to do that. When I've been working with St. John Ambulance I've seen somebody on 3 days without sleep and they were very very ill. Basically asleep but on her feet, couldn't feel it when we were pricking her with injections.

In a way it *is* like improved caffeine - longer lasting, and you do feel clear minded, but it is not a substitute for sleep.
