I am now 6 months since my surgery. The first 2 months were great then Mid April I started being very sick and could only keep down 1-2 oz of food a day. Even water would come back up. Well low and behold I had the old gall bladder issue. After the surgery in June I have been able to keep food down. I have lost a total of 105 lbs. 51 lbs was pre surgery. I haven't been back to the surgeon since my gall bladder surgery and I do not weigh unless it is at his office, so I am hoping when I see him next month I will have lost more. I am nervous because I am eating more than 1-2 oz of food a day now. But I do exercize 3-4 times a week in the pool because my back and knees are injured and I cannot walk. I have seen comments about the 5:2 plan and I would like that explained to me. Could someone help? Thanks, Maggie
