You know - I am a D -- but since starting the diet - I have had a couple times where I swung over to C. I would prefer to be C --- it doesn't hurt as much --or for as long. When I have a full blown D attack I am cramping so bad - feeling all hot -- and stuck in the bathroom - sometimes for an hour or more.... and then the ache in my tummy can last for up to 4 days later. When I'm C (and it may be because I'm not truly a C) -- I just don't go for a couple days. I may get bloated and not feel very well -- but it doesn't have the intense pain or the total stop of all activity but bathroom visits like my D attacks.
