I'm on Adderall now, but my doc says Modafinil works better. Have you all seen advantages of modafinil (which, as I understand it, is the generic of Provigil) over adderall? Which of the 2 am I morely likely to build up a tolerance to? Since Modafinil commonly counteracts birth control, it seems the ONLY birth control I can switch to is Periguard, since all others are hormone based. Anybody with experience with this or other forms of birth control on modafinil?
