chronic fatigue syndrome
"I started out on 100mg in the morning.   I was falling asleep an hour later, so the doctor put me on 200mg.  I still was very sleepy, but then the sleepiness would wear off.  I drove about 60 miles into town and I was driving very fast and taking risks I would never do normally.  It also made me want to buy lottery tickets. The increase of compulsive behaviors is very true with this medication..
I stopped taking it immediately. It was too expensive anyway!"
