insomnia
"I had been on this medication in the past and discontinued usage after I got pregnant. I  started back a few months ago, not realizing what the side effects were. I started gaining weight incredibly fast with no change to my diet and exercise and wasn't going to the bathroom unless I used a laxative. I was stumped and depressed about it up until yesterday when I spoke with a GI doctor. FINALLY I had an answer only after many visits to my family doctor and many co-payments which added up quickly (with no solution). Needless to say, I am so relieved to finally know what is going on with me... 20 lbs later but I see the light at the end of tunnel. Hope this helps."
