I'm prescribed two 20mg XR capsules and a 10mg instant release tablet per day. I have an exam I need to study for and was wondering what dose I should take to pull an all nighter and still feel the Adderall for my exam at 10:20am (it's currently 11pm). I think I've tried 20mg at this time before and I crashed about mid-morning, so I'm guessing I should try 40mg but do you guys have any suggestions of what I should do? I did get a good night of sleep last night and can get more sleep tomorrow after my exam, so sleep deprivation isn't something I'm concerned about since this will only be one night. Any help would be appreciated.
