I have to tell you, I just took mine out last night but I only had it in 3 months. I gained 5 lbs. Not a big deal right? Well I had one shot of the Depo Provera and in 3 months I gained 50 lbs. That was years ago (7) and I have not been able to lose more than 20lbs of that weight.( I was never more than 120lbs) I don't know what it does to us with the weight but it feels like it made my metabolism slow way down. I think if you can do something to reverse your metabolism you will be fine ( without more drugs). Good luck to you.
