I am also for trying the diet. I never got diagnosed myself... I just got an allergy test back saying I was slightly allergic to wheat so my naturopathic doctor suggested I eliminate it. What a difference it made! After 30 years of constant sinus infections, constipation and anemia, it all pretty much went away! So whether I am just intolerant or full celiac, I don't know, what I do know is that it is really bad for me.
I have been on the diet (though I've not been truly strict, i.e. I have had very tiny amounts of gluten till now for example in soy sauce) for about 1.5 years. But then during December I got tempted a few times to eat a bit of wheat (also encouraged by friends who don't realize how bad it can be). At first I figured everything was fine since I really did not feel bad after eating it, but by the end of month I got my first sinus infection since I started the diet. I've now been sick for 2 weeks and all because I ate a few bites here and there.
So, now I am more determined than ever to stick to a gluten-free diet, which btw I have no problems with. I eat like a queen and my boyfriend can't even tell the difference between when I baked with flour and now Takes a bit of adjustment but that is all.
