For the last couple of weeks I have had a bout of awful stomach cramps, nausea, wind and occasionally diarrhea lasting 1 to 2 hours almost every day.
I thought it was coffee so cut that out one day. Felt fine the next day but bad again the day after. Had coffee again and felt fine. There doesn't seem to be any pattern to it. It started off being in the morning but I've also had a couple of episodes in the evening. I've had it on days when I've eaten very little and days I've eaten plenty. Didn't have it the evening I had a big meal out and drank lots.
I feel completely fine the rest of the time but horrendous when I get it. Any ideas what it could be?
