Anybody has ever tried them? If so:
I have 3 final exams in the next 4 days, and I have to stay awake for at least 3 days and sleep in the 4th, is it good for me in this situation? Does it keep me focused?
Does it have dangerous side effects?
Do pharmacies sell them without medical permission?
If I do take them, can I drink coffee/Redbull while under their effect?
