I take 1/2 a child's dose of generic zofran if needed.. But it can cause terrible constipation.. so I use it sparingly. I have found that if I feel bad anywhere I interpret it as nausea. Trying really hard to work on that, still have a ways to go. I love love love coffee but the caffeine can really trigger the anxiety and nausea. You are so young, have you tried CBT? You can get home study programs online, I did this years ago and it really helped, the phobia and anxiety even went away for several years after I went through the program but has recently come back, but I'm coming out of it again! You can beat this!
