I will try to answer all questions about nausea, vomiting, and emetophobia. I know many ways of preventing vomiting (or bringing it on). I have not vomited in over 40 years.
For over 19 years, I have answered questions about nausea, vomiting, and emetophobia on the internet. I wrote the Emetophobia FAQ (Frequently Asked Questions About Emetophobia) and the Vomiting FAQ (Frequently Asked Questions About Vomiting). I wrote the first website about emetophobia and started the first mailing list about emetophobia. Both are still in existence. I am moderator of the largest emetophobia site.
I have a bachelors degree in computer science. I have studied nausea, vomiting, and emetophobia for over 30 years and have read many scientific articles about everything from morning sickness to space sickness.
I have helped thousands of people with questions about nausea, vomiting, and emetophobia, either directly or through my website.
