Question Re: Candida killer herbs and Left sciatic pain, Jhuan (sp?) and other please

Does anyone here know why my left sciatic pain always kills
me when I take anti-candida herbs. I know that killing the
candida uses up lots of minerls, etc. but cannot figure out
which ones. I have been doing major cleansing--metal removed
from 17 teeth over the last 5 years, did parasite killing,
13 Liver Flushes and now I am left with severe BRAIN fog.
I was doing 3 -4 coffee enemas per day and thought they were
harmful and stopped doing them. Now I read that Jhuan says
they can help brain fog. Please help!
