Hi Law,
Glad to hear that your husband's sobriety has brought peace and tranquility to your house. My husband is also currently sober from alcohol (though not for a medical reason), but because he is doing it for me. He also does not want to join any support groups. I do believe that a life threatening situation like your husband's can bring on longterm sobriety without any outside help. My husband's recovery, however, is more precarious since his bottom was not as serious as your husband's, and so I think that a program would benefit my husband. Good luck!
