I have been on the pill for 4months and I have gained 2stone over these months. I have as much exercise as i can handle, hasn't descreased my weight. I've tried going on diets, but after a day i give into my food cravings. I know the birth control makes me think i'm eating for two. I recently found out that hoodia can suppress appetite and i am VERY keen to try it, but I don't know if it will affect my hormones and birth control pill. Does it??
