@junita - There are so many of us with IBS! It is hard to get a grip on what to do because the body doesn’t always react as predicted. I’m glad to hear that you are planning a keto diet. I started one 2 years ago, successfully losing weight and keeping it off. I found that my insides were much happier on that diet. It definitely helped controlling the carbs.
Good luck! Are you using Imodium for the diarrhea?
