Only a small percentage of people gain weight, and if you do, you can stop and it is reversible...the mechanism seems to be metabolic and probably some psychological stress eating, if that is already your pattern.
I too am very sensitive about my weight and body image. I can relate about a slight increase. Many people don't understand that.
I was asked to take ciprimil and took it for five weeks.
I either lost or maintained weight on this medication. I didn't notice any increase in appetite.
