Hi fellow cfs and FM sufferers. I never thought I had this but after doing this test I found out other wise. So maybe a few of you might want to do this test and try to follow a yeast free diet for a little while (I have tried it for about 1 wk and I feel a little better) good health to you all! candida yeast overgrowth and not another problem. To do that, you need to take the following spit test. Will You Pass This Test? This simple spit test can determine if you’re actually battling candida. First thing in the morning, before you put anything in your mouth, get a clear glass of water. Work up some saliva, and then spit into the glass of water. Check the water every 15 minutes or so for up to one hour. If you have a candida yeast infection, you will see strings (like legs) traveling down into the water from the saliva floating on the top, or “cloudy” saliva will sink to the bottom of the glass, or cloudy specks will seem to be suspended in the water. If nothing develops in an hour, you are probably candida free.
