So i need opinions.. (Depo provera users)

I was on depo for 4 years never gained weight while on it, in fact, lost weight. Got off last February and gained 60 lbs roughly, been doing research that cases like mine, the only way to lose the weight gained is to get back on it. Has anyone ever gone back on depo and lost the weight? I'm curious and going to call my gynecologist in the morning and have an appointment May 20th as well, but just want to know if I'm the only one..
