I had a boyfriend once who would immediately start dry-heaving when he was upset. I get really nauseous when anxious, and I have emetophobia, so it's a vicious cycle. ativan helps immensely (though I think it's a pretty evil drug). zofran shuts down my nausea completely, which makes me less anxious. besides medication, I find cold water (splash your face with freezing water or take freezing shower if you're at home) and breathing/mindfulness exercises very helpful. also - distraction!
