Re Phillip Seymour Hoffman...I heard the other day that his wife had only known him in sobriety. They were separated when he began drinking again, and started his ultimate death spiral. It seems he would take care of the kids, get them off to school etc, sometimes have lunch with his daughter at a fave local place....then when he was alone at night be back at the same place in his cups, mostly keeping to himself. So talented and troubled.
Interestingly, if you haven't seen the movie "Don't Worry, He Won't Get Far On Foot" (Joaquin Phoenix stars as the main character who has a life changing event at the opening of the movie, Jack Black has a small role). PSH plays the unconventional AA sponsor whose higher power is named "Chuckie." Def a recovery movie worth checking out on Amazon or wherever you find it.
