I have a friend who positively drinks too much. He's not bad as far as getting too inebriated and acting erratic and crazy or abusive, but he gets canned just about every single day. He once told me he drinks so much and so habitually that he no longer gets sick or gets hangovers. His alcoholism doesn't affect his work or too much of his home life, but it has to be DESTROYING his liver. He also is not to keen on the idea of rehabilitation seeing as he hasn't seen it affect his daily life much. What on earth am I to do to help?
