I wish I'd figured it out myself. One problem was I was recovering from Celiac, and tried a very restricted diet, and a liquid diet - which actually worked when I started doing chicken in a blender (which is much better than it sounds, especially when you've been starving for 4 months). Tell a doctor 'I was starving and I went to this weird restricted diet' and it seems they have a really hard time with the order of things. Reality was "I was starving and in pain and then I tried this restricted diet" and they hear "you were on this restricted diet, and then you were starving and in pain".
