I've had IBS-D for years, and used to get loose stools every day. Recently it's been better, even sometimes going to C due to diet - and not eating much.For some reason today suddenly I had a really noisy stomach, then went to have D, been twice now. Very bad cramps - but they seem to be easing a little. Second time not as watery/loose. Taken one Imodium for now.I don't understand why it's just happened out of nowhere. I have started having one date a day with my porridge and raisins to help me stay regular. Maybe that was too loosening? Can it just suddenly occur?I'm emetophobic so I am scared it is a stomach bug. I'm sure I've actually had it before... but it's been such a while since I've had it, you know? So I can't rationally remember.
