birth control
"Gained over 10lb in two months even though I had no weight gain on the usual pill. I was going to the gym most days and whenever I ate I could never feel full. As soon as I came off the implant I lost 4lb within a couple of weeks. It has been harder to lose the weight alone and I maintained the same weight for over three months before losing some more. It was impossible to stay on this implant without gaining weight."
