Hi and welcome! I've gained weight and my clothes got uncomfortably tight, too. I joined Weight Watchers 16 weeks ago and lost 15 pounds so far. Now my family doctor told me to go on a low cholesterol diet because my cholesterol had shot up, so I'm making more changes to my food choices. I guess that my solution to weight gain while taking an AP is to be deliberate about what and how much I'm eating and also increasing my exercise.
