I have been overweight since I was 10 (maybe), at least that was my first diet.  I'm not sure now that I needed it then, but I was at a healthy weight at 16, but slowly gained about 20 lb over college years.  I took Depo-Provera for 1.5 years, and in the first 6 months, I gained 90 lb., and over the next 2 years, another 60.  I was in such a deep depression, I didn't even realize it was happening.  Incredulous?  Being chemically depressed does that to you!  I gave up trying to battle the weight many times over the 9 years since then, but I tried TOPS for a couple of years, and lost about 40 lb, but life happens (another baby!), and I couldn't keep doing that.  So I gave up again!  I'm now using Hcg to help me lose the fat, and it's working :)  So my weight chart is very sharp, and then static for a while; repeat :)
