I too get really nauseated when anxious and then worry about throwing up which just makes me more sick to my stomach. One of the things that helps me is to have a bag close at hand and to know where all the trash cans are so if I do throw up it won't be that big of a deal. Also I'll sometimes have someone there to help keep me distracted by asking me questions that I have to think about. Especially math questions. Some simple like 2 X 4, and some more complex like 12 X14. It works best if they are questions that I can answer if I think about them.

Hope that helps some

Congratulations and good luck.
