anxiety
"I have taken this medicine for 7 years. Gained lots of weight, now on Weight Watchers Diet and lost 16lbs so far.  Very happy now. At 45mg had bad restless legs, reduced to 30mg and sleep great 9 or 10 hours. Had intolerable insomnia my entire life before.  Wonder what would happen if reduced it to 15 mg. Also added 20 mg Prozac for daytime energy and works great."
