Two things I have discovered from trying to be gluten-free.

For the first time I have a consistent way to get the belly I have had for more than 20 years down.
Trying to not eat late, or too much, or fatty things never worked for me (partly cause I couldn't do it consistently). But now since I don't eat pastries and bread and pitas it's going down automatically.

Second - a great way to make wraps or sort of sandwiches - use this thing called rice paper.
