I had a 40-a-day habit for 25 years; stopped in February 1994 and haven't smoked since, except in my dreams! Always such a relief to wake up and find it was only a dream. And yes, I did put on a lot of weight - knew I probably would, so took care to lose a couple of stone before I gave up. That was through eating low fat, as was the fashion in the 80s and 90s. Then when I got fed up of being really obese (I think that, at my worst, I was over 100 kg!), I went on a low-GI way of eating, and lost about 30 kg. About 20 of that went back on, largely because my health deteriorated and I had to stop the ice-skating that had kept me fit for 20 years. Then, among other issues, I was diagnosed with T2, and a few years later was invited on to the Ascend Plus trial - I am obviously on the medication rather than the placebo, as so far I have lost about 20 kg, and have only 1 kg to go before my BMI is in the "normal" range. I also try to walk every day, and do tai chi at least twice a week (this has been totally transformative for my health).
