I've been on and off it for 10 years now. I have ADD and i take 30 mg twice a day. I feel ok now, i still struggle with it cus as soon as the pill kicks in im good for a couple hours then hit that low until i take the second one, then the same thing. But i have found out that the adderall extended release works alot better than the reg. one. The reason im not taking it cus i don't have any insurance and can't afford it, but if i could i would. And if your just starting out on it its going to take a little bit for it to get into your just system and your brain to adjust to it. I would just keep track of how you feel and im sure your doc can help u find something that works, best of luck to u :-)
