I think you mean Ryan from this Drugged episode. He did not die from alcohol withdrawals - he made it to like the 20th day. He actually died from a depressant overdose (possibly benzos mixed with some other depressant), administered to him by the careless staff. He was actually not the only one who died that way, AFAIK, although I can't remember the source I read it from - sorry.
But nonetheless, alcohol withdrawal is nothing to joke about, and it can potentially kill you.
@Moreaux: I'm not familiar with the pharmacology, will a regular antiseizure medication like the ones you listed help in alcohol withdrawal against seizures, as benzos would?
The rehab I attended twice frequently gave out either Dilantin or Depakote to us drunks, so I guess they are effective enough. Imo a benzo would have made the experience much more tolerable and it would have prevented the glutamate over activity which ends up having a horrible cascade of nasty effects and neurotoxicity which takes significant time to recover from. I think now they use phenobarbital and that seems to be more effective in terms of comfort, than just an anti siezure meds alone.
I think benzos are preferred because they are similar to alcohol so they can essentially be used to do a taper so it's not such a systemic shock and it makes withdrawal and subsequent PAWS much more tolerable.
