Creative alcoholics

I thought this chapter was amazingly interesting, particularly the part about alcoholism. Alcohol is a drug, is addictive, and alcoholism is a disease. Completely surprising was the information about some of the great writers of the 20th century being alcoholics. Hemingway's alcoholism, along with many other great writers, likely lead to breaking down of inhibitions as the book says. I should admit, when consuming alcohol myself (in small amounts) I feel much less inhibited, ideas come to me more easily and I can write with greater ease. Somehow my vocabulary expands, and my creative side comes through. Keep in mind, this occurs only between 2-3 drinks. After that, forget it. Concerning creativity, I wonder if there is any connection between sensory loss, schizophrenia and alcoholism? I believe there must be some type of chemical breakdown, or change, that all the episodes in chapter 9 discuss like epilepsy and alcoholism, leading to a creative element that the 'normal' (as Hughes puts it) brain cannot process. Thoughts?
