Follow-Up: Hi. I just started taking Provigil this Tuesday. I am taking 200mg./day. So far I haven't noticed any bad side effects. I have noticed a stong oder from my urine and I have been having some lower GI problems but I can't say that it's the Provigil causeing the problems. I also can't say whether it's helping me feel less tired either. I've been going through a bad sleep cycle ever since Sept 11th. I'm one of those that can fall asleep initially but wake up in a couple of hours with a head full of chatter.
