I have a friend exactly like that Mark...Great guy...Get's a few months...Bang...There he goes.....Been doing that for 10 years.....Won't do his fourth step. I was talking to him after a meeting one day and I told him..."You're constitutionally incapable of getting honest with yourself"...And he looked at me and just said..."I know." Maybe one more trip to jail or waking up on the streets one more time will do it for him....I don't know.
