Hi Chris. Sorry for the late reply, haven't been back in a while. No, I never did ask him if he had ever used fasting for someone with this specific set of symptoms that I have.
I sent him a VERY detailed email message detailing my condition- symptoms, past treatments, herbs/supplements used, length of illness, etc.
It was from this information that the office wrote back. They said that Dr. Fuhrman had read my email and that he did not feel that fasting would be of benefit in this case.
