Your questions about travel and finding food is a very good one. I have learned to travel with some food and then depending on where and how long I am going to be away from home I have food shipped to the hotel that I am staying at and also search out stores (on the web) that carry gluten-free food so that I can buy food. I have traveled to England and across the USA since I was diagnosed with Celiac and have found that if I explain to the waiter/waitress what my needs are they try very hard to find out if an item on the menu is gluten free. I have had chefs come out and talk to me about my needs or bring out an item thats ingredient was in question. Learning to live with Celiac is not easy, however, it is getting easier as the public, airlines, stores buyers, and resturants are being educated in a Celiac's needs. Do travel, don't be afraid to explain what your food limitations are and what you can eat as most places want your business and they will try very hard to meet your needs.
My biggest challenged has been with family and friends who don't understand how a little of something (gluten) will make me so sick.
I still miss going out for pizza, a quick meal from a fast food chain or just being able to pick up a food item at the grocery store without looking at the label.
Good luck is your endeavers. You will make it once you resolve that eating gluten free food is what you have to do to survive. The alternative is not pretty. Virignia, fellow Celica
