No. But I don't like any more than 100mg, and 50mg does wonders for me. When I take 200mg, I usually get a headache towards the end of the day. Actually I prefer armodafinil 37.5mg (1/4 of a 150mg tab). 50mg modafinil or 37.5mg armodafinil brightens my mood and energizes me without any negative side effects. I also drink coffee daily.
By the way, if you take alcohol while on modafinil, it puts you into a zombie like state not unlike drinking while on benzos. I once blacked out, walked away from a group of friends in a zombie like state, and "woke up" walking on a busy sidewalk on the other side of town. When I woke up, my eyes were sort of lazy and would involuntarily trail off, meaning I had a hard time looking in the same direction continuously.
