Hi, I managed to lose a lot of weight with ww 7 st I was only 18lbs off my goal weight when I stopped going and gained back 2.5st's I went to the Dr's last week because I was so fed up with myself and he prescribed me some reductil to try and help me get back on track. I've been on it just over a week and have lost 5lb, maybe you could speak with your Dr just to get a helping hand.
What I found helped the most was cutting out alcohol for a while (which I have to admit has crept back in again more than ever

)
The golden rule though has to be always write down what your eating even the bad stuff, I use the cookbooks a lot because I have a big family and I can cook something for nearly all of us out of them and the portions are much bigger than the ready meals which you can buy.
Good luck,
Helenxx.
