You might need to go back to your doctor and have them check the fluid in your band. I know I waited 7 months to go in when i gained 20 lbs back. I found out that i had 1 and half cc less than i should have had. I guess my body absorbed it. You will gain muscle mass, but muscles do help burn more calories. I also have PCOS and carry my fat in the belly and yes I am having a very hard time too. We must not give up and keep at it and the excercise is a must for us both...........
