How are you gaining your weight back? I'm 6 months post surgery but stuck at weight gain. I need to gain 13 lbs to get back to my usual 93 lbs. I'm 4'11" and have been in the 90s my whole life. I'm not losing, just stuck. Thank you for any hints you can give me. I count every calorie and gram of protein. Also, I'm on Zenpep, 30,000 units per meal, 10,000 per snack. If I go up to 40,000, I get the big D. So my bowels are beautiful; my body is awfully thin!
