Your symptoms are pretty classic for candida overgrowth. Unfortunately the spit test should not be used for diagnosis:
We developed this general plan to get better if you are interested:
If you start to feel worse, then you know it is working because it means that the candida is dying. When it dies, it releases hundreds of toxins that make you feel bad (generally similar to the flu). If you protect your kidneys and liver, this will make you feel better (by detoxing the toxins). If the toxins remain the body, you will feel bad.
