I went in for my follow-up consultation with the progressive doctor yesterday. I was able to report to him, before we went through my test results, that I feel better (much much better) and have even lowered my Elmiron dose! (I'm taking only 100 mg a day now, and skipping doses without noticing!)
I've also started eating citrus again, with no negative effects. I love limes in my water, and I have an occasional orange!
He asked me why, and I think it was a combination of getting a strong source of protein and iron, and eliminating all grains. In fact, when I would eat a gluten grain, I would even start to feel a little sick. So my body is telling me what to avoid!
