Starting 8 years ago, my digestive tract gets out of whack once every few weeks. I call it a "toxic reaction" because it feels like food poisoning. I get abdominal pain, diarrhea, low-grade fever, and a strong sense of physically being out of balance. If it's bad enough, I'll spend half the night vomiting. After 2-18 hours, I start feeling better. In between reactions, I feel fine & have regular bowel function.I've been fine-tuning my diet for years. I know dairy is a trigger. The weird thing is sometimes I can feel the reactions starting 3-4 days ahead of time, and those don't seem diet-related. For the last couple of years, the reactions haven't been as painful, but they've been more frequent and I am sick to death of never knowing when I'm going to be throwing up till the wee hours.I've been to a couple of GI docs. I've had a colonoscopy and small-bowel follow-through; all looks normal. My current doc says my symptoms aren't typical of IBS, but that's the best fit he can find. He says I don't have CVS.What I want to know is -- does anyone else out there have a pattern like this? If so, what has helped you? Doctors can be useful, but there's nothing like going to the horse's mouth.Thanks.
