I am on antibiotics for a sinus infection, and find Phillips Colon Health probiotics suit my system the best. Others I tried didn't work. Probably due to the tramadol I take, I never get the D even with antibiotics. Probiotics is keeping me going and not having excessive gas, although I also avoid gassy foods!
I am lactose and sulfite intolerant. The only yogurt I tolerate is Activia, and that will give me bloating if I eat more than 1 small container. It also helps my gut where others didn't.
I have trouble digesting beef. Oatmeal every morning helps keep things regular. I can't take sauerkraut or onions because of the sulfites.
