Awww, Im sorry. I feel for you. Were you given a diet to follow? Try clear liquids for a couple days and see if that helps. Sometimes medications can take a couple months to kick in. I know how you feel about
losing weight, Im 60lbs overweight , even though I have constant D. Try eating small frequent meals 4-6 a day. Try to stay away from raw fruits and veggies, they are hard to digest. Smoothies, broths, jucies. Drink a lot of water to stay hydrated especially if you going a lot.
