"I've been on the Depo shot before and other than slight (maybe 3-5 lb) weight gain and slight mood changes I had no problems with it. I was off of it for about 5 months and just got back on it and in one week have gained 27lbs and get skin rashes pretty consistently now. My mood is ridiculous; I cry like every day, sometimes out of happiness, other times out of sadness."
