I think the issue of having to restrict what I eat even further is what had me dragging my feet to change. I'd already cut out most processed foods, except what slips in from the occasional restaurant. When I became more sure of what wheat was doing to me, and I'd already figured out many foods I could make myself at home that had no wheat, I had little problem going wheat-free. I have encountered a few obstacles at restaurants, and that's taught me to be more careful. I have heard from others who have decided to never go to a restaurant again, or to not order anything when they go out with a group of friends.
I also follow the principles of the Weston A. Price Foundation (www.westonaprice.org) and have been feeling better nourished on that...but I felt like I was still not absorbing things very well.
My face isn't making a magical, overnight recovery, but like you said, it's not getting worse at this point. It seems to be healing. I did get a new zit on the temple, but no new ones around my mouth at this point. Plus, Acne seems to be related to the liver, intestines, those systems...so there are probably indirect causes & interactions...it could be mostly the effect of having the bowels moving better.
But yes, I think only a serious gluten-free effort can do anything consistent for the Acne problem. I was only having occasional wheat, I thought, but I think it was more frequent than I wanted to realize. I have been keeping a food diary since gluten-free-ness. Yes, it's all work, but it's work that is healing me, and I am just scared of the effects I already see happening. My hair is going gray more and more. My bowels have felt inflamed recently...not all the time, but there's just been enough signs to scare me about things getting worse.
