Is there a possibility that you have an inherited neuropathy, such as Charcot-Marie-Tooth (CMT) disease, that might cause you to be more susceptible to nerve damage from alcohol? There is debate about whether people with CMT are more susceptible to nerve damage from drinking alcohol, and perhaps it differs depending on the type of CMT. In my experience, it think it is highly likely that amounts of red wine with dinner that would be no problem for others contributed to nerve damage.
