I'm sure it would make me feel better about myself, its just finding the motivation to change my lifestyle I guess. I stopped drinking and smoking quite successfully in the past, I should probably do that again. Dieting I find somewhat more difficult because I comfort eat, and I enjoy food.
I think I once topped at out 22 stone, I have a deep and lasting love for unhealthy food. Going to the gym is the only thing that stops me from returning to being the size of a house. I gym so I can eat!
