I stopped between one day and the next. threw out all the bread and flour in my house, cold turkey, done.
I am somewhat familiar in a few different ways with addiction, and stopping entirely is the only way to break an addiction. If you feed it even a little bit now and then it will come back full force.
I also stopped abruptly because the reason I stopped was that a naturopath told me to try it to see if it were gluten intolerance causing my gastro-intestinal issues. The only way to know was to stop it completely. After 2 weeks I was so much better that I knew that had to be the key so I never ate gluten again except for one time when I sort of tried it out and felt as if I had the 'flu the next day.
I will admit that my addiction to bread was major. It had always been my favorite food, since I can remember, and I ate a lot of it. Not sweets or anything, just whole grain or sourdough bread. I baked my own. It was very healthy bread, but that makes no difference if you are gluten intolerant. For almost a year after I stopped I craved bread every single day. I didn't try gluten free bread because I was afraid that
any bread would only lead me back into that addiction. After the first year, the cravings stopped and I never thought about bread again.
I never wanted to eat gluten free breads for fear it would only start that craving again. But several years past my giving up all bread entirely I decided to try one piece of gluten free bread, and it didn't bring back that craving so I very slowly added that to my diet. Now I eat gluten free bread although not as a major part of my diet, and I will go days sometimes without even wanting any. I think for me it took that time period, though, to break the daily habit and I am glad I went through that.
