HAd surgery on December 10, I was able to lose the recommended 10 lbs before and have lose 10 lbs after. Don't recommend having surgery at the end of a cold . I never felt so thirsty. So far so good . I see the surgeon this coming week and I definitely am beginning to feel hungrier . I weight 220 and it's been over 20 years since I was under 200. Trying to keep on track
