I dont have A.D.D., i might get flamed for asking this question

but I need to cram badly for my calculus exam, and I asked my sister (who has A.D.D.) if she has any medications. She gave her a bottle of her expired dexadrine 5mg tablets. Theres about 40 of them.

How much dose should I take to study? BTW I am planning to pull 2 all nighters in a row, exam is on Tuesday morning.

I am sorry you felt the need to post what you did
