How did you "aggressively" treat the candida?
I saw a qualified dietician. We started out with a food diary and then I was put on a very, very strict no sugar, no moulds/yeast diet. At one point I was on a strict exclusion diet which reduced me down to 16 allowable food items one of which was bottled water! Anything drink with fizz or bubbles, including sparkling water, was banned.
I was also treated with several courses of diflucan and then when symptoms started to creep back a couple of courses of diflucan in combination with another anti fungal drug whose name I just cannot remember. We then tried some probiotic treatments to try to encourage the "good" gut flora (I reacted really badly to a couple of probiotics though).
I also had breathing and relaxation/postural exercises to do. I have a history of asthma and the dietician thought it would be useful in case I was "overbreathing" from habit which can cause blood chemistry changes and cause imbalances in intestinal flora. This was supervised by a physiotherapist.
As long as I stayed on the very strict yeast/sugar free diet my symptoms improved dramatically. As soon as I introduced yeast or sugars (even post anti fungal meds) the problems would come back. At that point the dietician felt we had done all we could.
In the end I remained on the very strict diet for around three years - even after trips to dietician had stopped. After this point I could have a little of products containing small amounts of sugar yeast and, as long as I didn't push my luck, that would be ok.
I also have to be very careful with refined carbs that turn to sugars easily. I have to view these as treats - if I have them too often or too frequently symptoms start creeping back.
It turned out that I am very sensitive to some of the foods and spices that my mother used in her daily cooking when I was a kid (& long before the idea of food sensitivities and allergies were acknowledged) I think this is one of the reasons why I was so difficult to treat.
I also had various deficiencies - especially the metals: iron, magnesium, manganese, chromium and zinc. I still struggle with some of them from time to time - especially iron.
Hope this is of some use. If you have any specific questions I'll try to answer them. I underwent treatment for this over 15 years ago so things may have moved on. This all took place in the UK and I have a feeling that the USA is probably ahead of us in dealing with this type of thing.
