My concentration is terrible. I cant focus and I have a little trouble reading. The words seem to jumble so i have to go back and reread what I've read several times even though I have 20/20 vision. I've had multiple tests, they all say my thyroid and liver functions are fine, blood-sugar is normal, cholesterol is great, etc. They just cant seem to find what the problem is. I'm a very active person, I jog about 6 miles almost everyday. Sadly I have to wake up at 4:30am or 5:00am to do it because there isnt anyone on the streets at that time. I'm currently only eating fruits and vegetables. For the past week I've stopped eating meat. Is there a treatment for yeast overgrowth????
