When you make most things from scratch, gluten can be easily avoided, and my girlfriend has already bought a variety of gluten free flours such as potato flour and even coconut flour (see www.goodnessdirect.co.uk). In some respects, my diet has probably become more interesting, lunches especially. No longer is it a sandwich everyday! The majority of recipes are gluten free anyway and most are easily adaptable. They're also perfectly suitable for anyone on a normal diet because you'll get more than enough in everything else you eat.
One of the foods that I would say I'd miss the most is pizza. My girlfriend and I frequently visit Pizza Express but unfortunately their menu is somewhat restrictive for me now. However, my girlfriend made a great gluten free pizza last week and you couldn't tell the difference. The base was a little lighter but tasted great and the tomato, mozzarella and pepperoni topping was a delicious classic. She cooked it on the pizza stone I got her for her birthday which cooked the base evenly and gave it a crisp finish.
We didn't have any dried milk but it didn't really need it, she just added a little extra flour to get the right consistency.
