I threw up almost every day from August to March, and my internist thought it was a Crohn's flare. Turned out to be gastroparesis, completely unrelated. You may want to check with your GI to see if there are other possibilities. Also, I'm told Flagyl can cause nausea and vomiting. Are you eating something with it?
Diagnosed with Crohn's in 2008 at the age of 22. Also dealing with gastroparesis & GERD.
