I Am 2 Weeks In To Diet, Am I Doing Something Wrong? in Coping with Celiac Disease Posted November 13, 2007 · Report to Admin It took me 3 weeks to start to feel better, but then I still had symptoms, sometimes severe. I originally just thought I was getting glutened, but it turns out I'm casein AND soy intolerant. It took a long time for me to figure out soy as a culprit. My next bet for you would be to eliminate all dairy to see if that helps. You can then reintroduce dairy later to see if you can tolerate. For some, if they go off dairy and gluten for 6 months they are then able to eat it again.
