Sounds JUST like me in the 80s. I tried that weight gain crap.

All I got was expensive stomach cramps. I was 6'5" and 139 at one point. NOW....I'm 6'5" and hovering between 208-215. Two years ago, I hit 227.......98% of that is in my dang gut! Good thing with me is when I get SERIOUS, I can lose weight. I have no problem walking or exercising. It's dodging food that TASTES GOOD!
