I have done SCD - read the book, did the supps (glutamine, molybdenum, etc.) and I can't say that it helped me much. I think many of the principles can be helpful and there are some that I do use to this day - if my stomach feels particularly taxed, I might due a few days inspired by the intro diet to get myself back to baseline - but I also found a lot of the "allowed" foods to be terrible for me. So it is a great way to find what works for you, but don't continue to follow any of the "rules" if they aren't working for you. Also, I feel like it's more geared towards people with IBS-D, not C.
Is it weird in here, or is it just me?
