I know it was taken off the list so I tried to word my comment carefully. Given the details of my history, I'm convinced that it was a factor for me. Of course, I might be wrong, but in view of my experience and family history I suspect that for a few genetically susceptible individuals the risk that modest consumption of alcohol poses for the nerves might be underestimated. Much as I'd like to have an occasional glass of wine, I have given up drinking alcohol altogether. I wonder if there might be a difference in regard to alcohol sensitivity between the different types of CMT. Do you happen to know of any research on the topic and/or the background of the decision to remove alcohol from the list? Also, in view of what Mrs. D. said, the particular type of alcohol (red wine) and/or B1 status might have been factor(s) for me.
