I have no clue if I am experiencing IBS, but I do think it could be something along the same lines.
I have been having a fast onset of diarrhea and vomiting about once a week for the past 3 weeks. This has never been a problem, so I am a little worried. It seems to happen after I eat. There are no links to the food (which would make me think it is an allergy). It almost seems like food poisoning, but after the 3rd time, I felt like something else may be wrong. It just seems to crazy to think I would be getting food poisoning weekly. Also, every time I have been eating the same thing as several other people, and I am the only one getting sick. It lasts for about 3 hours and is very debilitating. Usually starts with painful cramps.
Anyone have any ideas what could be going on? I am going to schedule an appointment with my doctor in the morning. Thanks!
