Oh yes, the weight gain!
When I had the sah I was dreadfully thin. I had a two month stay in the hospital, was fed through a PEG for a while, but when it was removed I ate everything I could, and gained weight before I left - the doctors were very happy, and I, although very happy to be going home, was rather miserable because none of my clothes fit.
For what seemed an eternity, my new 'stay at home sedentary lifestyle' meant I was home 24/7, most of the time alone, and free to eat whatever was available. As it turned out, I had developed quite a sweet tooth too, and a growing waistline.
Fast-forward almost 20 years, I've improved my diet; I have relearned how to walk, and as a result have bought a treadmill, (Still have to hold on for dear life!) and what's called a "Resistance Chair" - I can sit down, (crappy balance) while I use the pulleys for strength training.I have lost about 30-40 lbs, (I haven't a clue how many stone that is!) and just keep plugging away at it. I exercise when I can, but certainly not as often as I'd like.
