Actually, an IQ of 175 would more nearly rank in the top 0.00002 percent, as would pretty much be true of an IQ of 168. An IQ of 140 or above ranks in the top 1/4 of one percent. I guess that makes us rarely gifted to have two incredibly rare IQs in the same thread when the odds are greatly against even a single IQ that high appearing anywhere on the entire site.
But the observation that high IQ does not prevent dumb actions is surely correct. Just look at the decidedly unhealthy protocol that has been proposed here to get rid of candida - with the justification that amounts to "I'm healthy enough to really screw up my health in a misguided attempt to accomplish something healthy".
To the original poster: what you are feeling are the results of a very unwise regimen. You did not get candida due to a deficiency in mainstream drugs (in fact you may have gotten it BECAUSE of mainstream drugs) and you are not likely to get rid of it with an excess of mainstream drugs, though the likelihood of other health problems is high and grows higher the longer you continue along such a path. My suggestion is to do a thorough fasting, cleansing and detox and then look for ways to naturally restore proper balance and address the candida through things like diet, natural pathogen destroyers, probiotics and prebiotics, coconut oil, bentonite clay, etc. And it would likely be a very good idea to include some good healthy items for your poor liver (such as the aforementioned coconut oil, milk thistle, selenium, alpha lipoic acid, curcumin, and beetroot juice).
