I have never thought of giving up flying. Even though driving and sitting can be a real pain in the ass (literally because I get really bad lower back pain and pain in my butt).I suggest that you try the site called "A New Way of Eating. It's a diet and cookbook by Heather Van Vorous. www.eatwithoutfear.com/eatcook.htm. It has some great stuff in it. You can probably figure something out to change your diet to allow you to fly. I take my own snacks on the plane. Good LuckTEECEE
