I would second you, cappy and seemkc. we need carbs this is sure. we should limit sugars, grains...especially during the treatment and some period after.
As I cant give an axioma :0 (I dont think its accurate :) I would say IN MY EXPERIENCE - very low carbs was producing more problems. I was reading that VLC can reduce also some parts of the imunity system and I believe it.
I just try to limit my sugars and bread etc during the treatment and to combine carb food with something esle when I'm eating them. A limit example: if I drunk coffee with Sugar alone(that was before ilness got worst) - symptoms were worst.If I drunk it togheter with food symptoms were far more "light".
I would pay attention on the type of carbs that'a all - trying to avoid the above and the easily to eat/absorb carbs/foods. glucose, sugars, cookies, floors....
