Ok, I know I need the antidepressant for IBS/Fibromyalgia/pain. I am just having problems sleeping with no resolve on Wellbutrin. I have been advised to try Serzone because of its ability to make you sleep, and without weight gain. Has anyone had any bad side effects on this medication? I realize no two persons are alike, but if I could just get a general idea how someone responded/reacted to it, I just might give it a try so I will not be up and down during the middle of the night, and can come into work and not have to go through the motions of pretending like everything is fine!
