My doctor at least believes in gluten sensitivity, so he told me not to eat gluten if I do better off of it. Truthfully, even if he thought sensitivity/intolerance was bunk, I wouldn't care. I wouldn't eat gluten again if someone paid me.
I have to keep in mind how miserable I was eating gluten. It was so not worth it. I also don't want to test the theory that gluten intolerance is "pre-Celiac"-- don't want to have full-blown Celiac down the road.
KMM, I think it really helped me to get rid of everything with gluten in my house. No temptation to eat anything with gluten. Also, it helped me to tell all my friends and family-- they're very vigilant on my behalf. If they see me eating something that looks like it has gluten, they jump in. I'm never eating gluten, but I'm glad that they're aware. If I ever did intentionally eat gluten, I'd have some 'splaining to do.
