So would I like to answer the vomit topic. I have been seeing some doctors the latest 3 years. They told me that I probably had IBS. During every visit I asked if vomiting is a symptom too, but they always ignored the question. You see, my problem is cramps and vomiting for may be 6-10 hours each time I get sick. I also periodically have some diarrhea, this alters with soft stool, hard stool and constipation. Every time I have this vomiting experience I am freezing so much my teeth are clappering. I also have a little fever now and then. There is also a lot of gaz after a meal. When I vomit I often do it after a dinner meal, and it looks like brocolli and some other vegetables (for inst. bambooshots) makes me vomit. I am often extremely tired, and have waaay too low iron levels.
