Well, he's handed over his ATM card, credit cards, and cash and asked me to hide them somewhere so that he won't have any access to money (and therefore temptation). He's also found a somewhat similar site to this in Russian and has been reading stories of recovery, relapse, etc there.
Today is day 3 of sobriety. I know from experience that this is usually when the withdrawals and moodswings start to kick in....
Praying for patience and strength today....
