Awesome. It has been a miracle drug for me. But don't take more than the prescribed amount--like BirdDancer correctly points out, it's just not good. I was in a very high Provigil dose at one time because my brain was so sick. Then, when I started to get better, that same dose was just too much. It totally over-activated me. Tweaking, basically, for me, anyhow. Not like Adderall at all--there is no euphoria from Provigil, at least for me. So, taking too much really is the worst of all worlds, even if you don't get mania.

Just a tip from someone who has been on it for a very long time.
