Hi!
I haven't been diagnosed with celiac but I am definately gluten intolerant! I had all of the symptoms of celiac from a young age. I have had lots of what you described, my doctors weren't as knowledgable as yours sound. And YES you will get better! I am so much better than I was! HW and the GF diet are what has done it for me. It does take time, patience and perseverence.
The one thing that I wish I would have done was the in between herbs that RG recommends. 1/4 tsp of onions, garlic, sage, thyme, ginger, cloves and cinnamon. You take them in between the HW cleanses. I really think I would have made more progress if I had done that.
Also, have you seen this? There is a link between celiac and a bacteria. One reason that I am continuing with the cleansing.
