i had my jpouch since 4.15.15 and I too experience hard times gaining weight. I dont get sick, but I just can't gain weight. I am 5'6 and 114 lbs. like to be 125 lbs in case i do get sick. I tried everything, weightgaining shakes, just the very best foods, nothing helps. It goes out as fastest it goes in. I do take paregoric, cholestyramine, lomotil and metamusil before every meal except the paragoric and cholestyramine, i take that in the morning and at night. so there you have it. Any sugestions or help is highly appreciated. the constant trips to the bathrooms drive me crazy.....
