I’ve been on Depo Provera for over 5 years. No complaints. I had extremely scanty/irregular periods before I started getting the shot (I only got a period about 3-4 times per year), and they went away entirely as soon as I got the first shot. None of the whacko side-effects that people have complained about (headaches, dizziness, lack of sex drive, etc.)
As far as weight gain is concerned, I actually lost about 40 lbs in the first year I was on Depo, but that was attributable to gallbladder disease. Since my gallbladder surgery, I’ve gained it all back. I’m trying to lose it again (and then some), but things are going very slowly. I’m considering giving up Depo in favor of the IUD, which is non-hormonal. Since I’ve both lost and gained while on Depo, I don’t feel comfortable blaming the shot for my weight, but I definitely think I’ll be better off if I can get away from the hormones.
I don’t have kids, nor do I want any, and I’m over 30. I’m hoping my gyno will consider me an acceptable candidate, since, as Nymysys pointed out, the risk of expulsion in people who have never had kids is lower as you get older and I’m not really concerned about the (minimal) risks to my fertility.
My IUD appointment is in 2 days. Wish me luck.
