Medroxyprogesterone
"I just had my 3rd shot and I'm very happy with it. Before I got on the shot i had tried several different pills. They all made me have mood swings and depression, and I felt tired all the time. My doctor talked me into trying the depo shot and it has been amazing. I feel full of energy and I haven't had any mood swings and best thing is I haven't had a period since!!!! The only side effect that I don't like is the weight gain. I have been working out like crazy to prevent the weight gain, which I haven't gained any weight but I can't loose any. So basically I'm working out just to stay the same. This sucks but if this is the worst of the side effects for me then I can deal with that."
