I've never had blood sugar issues, but I have lost quite a bit of weight since late February, when my previous sober streak started. Has greatly improved my health in many ways. I was going low carb for awhile, under 50 carbs a day, but my body didn't seem to like it. Couldn't sleep, feeling rundown all the time etc. I seem to do a lot better keeping carbs between 100-120 a day, still relatively low compared to the normal American diet. My Fitness Pal has helped me out a lot on all that food and nutrition stuff, tracking calories, macros and whatnot. I'm 60 pounds down total, got my blood pressure normal, feel a lot better.
