I have the same issue but I have been doing better since NB. have you tried different forms? I know I can handle beer better than wine. Wine makes my muscles cramp up and hurt, but one beer is okay. Or even a small mixed drink. Sometimes I think it's the chemicals. I started making my own wine last year so I'm anxious to see if I can handle that.
I think the intolerance will go away once the AF is cured. I've had intolerance problems in the past and it always gets better when I address adrenal issues.
