I am very sorry to hear that you're feelingly poorly. When I was feeling my very worst, one year ago, I was suffering from candida induced hypothryroidism. I had many of the symptoms of hypothyroidism, alhtough my thyroid panels always came back "normal". Do you think you have the symptoms of hypothyroidism?
It's purely my personal opinion, but I feel that true systemic candida is rare. True systemic candida is usually only found in people with compromised immune systems. Since I believe that in the vast majortiy of the cases candida is restricted to the interior of the intestines I made not overly concerned about blood Sugar levels.
BTW, I've gone through some tough times of my own over the past year. You certainly have my sincere sympathy and understanding. I wish it was in my power to ease your suffering. Given the severity and duration of your case, what attempts have you made to enlist professional medical help.
