hey nick, if you are intolerant to drugs and herbs that kill yeast and fungus, you could try intervenous hydrogen peroxide therapy. it's a bit pricey, but works wonders. you should do some research on the subject and see if it's right for you.
not only did it get rid of my yeast overgrowth, but actually helped clear up my lungs after i quit smoking, and so many other things. i feel like a new person, completely healthly and did it all drug free!!
