until 3 months or so ago, i was a serious fun-loving boozer (vodka). i knew it was doing my legs and feet harm but i didn't care until one day i woke up and a/ could no longer feel my toes at all and b/ numbness had spread up my right leg and started in on my fingertips. i have zero will power over booze, so i called the doc and got a scrip for antabuse, wherein you throw up if you take a sip of alcohol.
about a month ago, mrs. d pointed out that antabuse itself can cause neuropahy, so i've stopped taking it, but i no longer crave vodka the way i did.
a single antabuse pill lasts two weeks, although you're supposed to take them every day. if i start to feel that crave again, my plan is to pop a single pill, which will keep me straight for the next two weeks.
the new numbness has stabilized but not gone away. i fear i've done permanent damage. that being the case, i would strongly advise you to do anything and everything you can to continue to stay clean and sober.
