That sounds like a great reaction to an uncomfortable situation. Last time I vomited it was similar in the sense that I went to bed a little off, and woke up needing to get sick. For me it took a few hours of diarrhea before I vomited, and the fear was awful. I am very interested in the contact info for your hypnotherapist. I am in cbt/exposure right now, but am not making much progress. Feel free to pm me (though I'm not sure how to pm others) or email me at [email protected]. I look forward to hearing from you.
