That doesn't sounds like much fun, I'm sorry .
My anxiety doesn't always make me gag, but it has happened before. It usually just makes me want to puke (among other physical symptoms). And sometimes I do actually throw up. That's not fun either.
I wish I had some suggestions for things that you could do, but I can really do is say that you're not crazy, and you're not the only one.
Hang in there, friend
