Hey, I've been looking for someone with my same symptoms. In July, it will be two straight years that I have been throwing up on a daily basis. I've been to several specialists and had tons of tests done, mostly by gastroenterologists but some by hemotologists and rhemotologists. Anyway, they've found nothing. I'm beginning to think that its something very simple such as acid reflux, because all tests for bigger problems, such as cancer, tumors, bleeding in the brain, ulcers, structural issues, that could cause the vomitting, have been ruled out. I'm going to try taking some medications for acid reflux and see if it helps the vomitting. I just found out I'm eight weeks pregnant and the acid is getting worse and worse. I'm 23.
