I recently got a prescription for Adderall. I've had trouble with procrastination and some other behavior typically associated with adult ADHD.
On a typical day, I'll eat a big breakfast, then take a pill. About an hour later I'll get a sense of euphoria and go into the zone. The euphoria wears off after another hour or so but for the next few hours I'm able to concentrate really well on whatever I'm doing.
The most noticeable side effect for me has been loss of appetite. It's kinda creepy for me to look at my watch, realize I haven't eaten in 8 hours, and not feel hungry at all. I also notice sometimes that I'm thirsty, but don't bother getting a drink because I'm too engrossed in whatever I'm working on.
greengirl512 is right though. I still have to force myself to start working. But once I start I don't stop. It's the same for books and video games too. In a way it's like replacing ADHD with OCD.
I think it's worth trying. If you're 21 and in college it shouldn't be hard to get a pill, but I would recommend scheduling an appointment with a doctor and telling him or her what you've told us. With most health insurance, a month's prescription will cost you what a single pill would cost you from a dealer.
