It sounds like you have everything covered. I think you're going to have a great day! I have emetephobia too. That is my primary, HUGE phobia... and was a major contributing factor in my 3 years of agoraphobia. You sound so much like me... I always have my benzo -- Clonazepam; my anti-nauseants -- Diphenhydramine, Stemetil, Scopolamine or Phenergan; and my natural remedies -- ginger capsules and little peppermints; as well as Nexxium (my GERD pills) and Imodium in my purse... just in case. (I'm a walking pharmacy

). I also keep ginger and peppermint tea bags and soda crackers in my desk at work. All those things are my "security blankets."
Have a great time at your wedding. Enjoy it! Congratulations!
