Hi,
I had similar symptoms you described. For a while i thought that dealing with the candida would fix everything, but it didn't.
I found out i've got too much heavy metal in my body, and from what i've been reading, it looks like the metal poisoning is the source of the candida, and maybe even the source of the alcoholism.
It sounds like you've been drinking & smoking for a long time. When alcohol & smoking are done together, your body has had the opportunity to accumulate a lot of metal, since the alcohol knocks down your liver function, allowing you to absorb more metals from the smoke. The metals from the smoke mix w/ the saliva, and enters your digestive tract, creating an environment that yeast like.
