Thanks all. Wolfy gave me the impetus, and he makes sure that I don't sit down too long, but it was also about a lot of healthy eating, cutting diet, and other exercise. I didn't have as far to go on my journey as people on this forum, who have started from much larger weights - and I hold those people with the highest respect - you keep going for it guys, you're the tops!
I'm not the finished product yet - I probably never will be, because I want to get even fitter, and to keep myself in a good state. I didn't finish a diet - when I reached my final target weight, I modified it - I still control what and how I eat, and intend to for the long term. I want to prove the skeptics wrong - you can lose weight long term.
