I too have 10 stones too lose, again. It is possible, it just takes a very long time. What irritates me is that I have done this once already, and put most of it back on. Once more into the breach.......
I want to lose a total of 10stone, I am 3stone down so far although I am following Slimming World. It looks like it's an endless dark tunnel but there is light at the end of it, break down your goal into mini goals, it makes your over all goal a whole lot less intimidating! I say half a stone at a time you can do it if you really mean it! x
