Yes, I had been off all grains, dairy, sugar, and soy for over eight months. I was doing better but still not GOOD. I was still having lots of unwanted symptoms. That is when I had the food intolerance and other testing done. I tested positive for many foods, I didn't even count them, several dozen but maybe a dozen or so which I consumed regularly. It was months before I could really say I felt better and I started gaining weight. Initially I felt worse, I guess that is what they call a “die-off” reaction which was horrible. For about 5 days I had headaches (which I rarely get), was very moody and extremely tired. I almost gave up, then it was done. I do still have occassional bad days; I need probiotics too which I have been having trouble taking due to reactions, which I guess can also be “die-off”, I'm working myself up.
All I can say is don't give up, it can be a very slow process. I have been going at this all for about two years (took the long road starting with “traditional” gf)….but after all this time I am having many more good days than bad whereas I had all bad days, maybe someday they will be mostly or all good.
