Welcome. The first year is the hardest. It takes time to heal & adjust. Cipro has some bad side effects. Read up on them. I can't take it anymore. The only drug I take for pouchitis is Xifaxin & Levsin. Lomotil stopped working on me. Took it for 20+ years. I guess it was good to get off it. Take OTC Imodium now. I like to have loose stools so I can empty easily. I don't put on weight either! Make sure you eat a low residue diet & chew your food well. Yogurt is great if you like it. They make a white fiber pasta now that is good too. Oatmeal is ok but don't overdo the fiber at first. Your body needs time to adjust. But everyone is different, some can eat anything w no problems. Not one of them. Over the many years, I have added allot of foods that satisfy me, Caesar salad, grapes & nuts that are chewed well, sweet potatoes but not too much, well allot but no mushrooms or popcorn.
More advise, go to sleep on an empty stomach. Drink lots of water. Good Luck, you are not alone!
