I know this probably belongs on /r/drugs but you guys seem more informed/sensible. I'm already massively behind on my course at uni and I really need to catch up. The probables is I'm already sleep deprived as shit so I don't think an all nighter with just coffee will help since I need to be able to concentrate for a seriously long time. I'm planning on doing a 16 hour+ session to catch up next week and I need advice on what I should take/dosages. I initially had the idea of xanax. But I'm on a student budget here so if there's anything cheaper that will satisfy my needs that would be appreciated
Xanax to stay awake? ... what?
Catch up with your sleep debt first.
Coffee < Modafinil < Phenidates < Amphetamines.
