To be honest I've been quite lucky as I've never had any tummy problems from the AD's, but then I have always taken them with a meal so they dont go down on an empty tummy. I'm currently on sertraline (lustral) but I used to take fluoxatine (prozac) but that didn't bother me tummy wise just gave me really vivd dreams and night sweats! My doctor said to take half a tablet twice a day as like you I was scared thay might upset me. All I can say is that even if they do hurt your tum to start with once they take effect you'll probably be less worried about the symptons they cause as they reduce your anxietys. Also you'll probably find yourself more willing to make changes to your diet and lifestyle, I know I did x
