Speaking as someone who has just started adderall, the side effects are not always the same. My doctor started me on an extremely low dose because of the side effects and we have gradually moved up from there. I do experience various side effects and we are dealing with that. People who take this drug don't realize that there is more than one type of Adderall -- not each type is right for each person. The type that I am on at the moment releases slowly but steadily, and I hardly notice any differences until I am about ready to go to sleep. Dosages also vary -- I am currently on 15mg but was started on 5; my point is that if you take this drug from someone illegally not knowing your threshold you could cause yourself more harm than good. I had a friend who decided to try it once and instead of studying she couldn't stop cleaning. If you're feeling stressed and like you can't handle your amount of work then go see the BU Mental Health services or speak with your professors - you'd be surprised at how willing some of them are to help you. If you get a negative response from your professor try going to your college's advising office (I know the people in CAS 105 are quite kind).
