I'm also a Christian addict, anon. I pray every day to be released from these habits. God has helped me, but I still slip up from time to time. All I can recommend is to continue praying and fighting the good fight: take it one day at a time, etc. Its hard, I know, sometimes it even seems impossible. But I have gotten better and look forward to the time in my life where I can claim true sobriety. Keep faith anon.
Part of what has helped me is keeping the designated fasts that us Orthodox have. Also, having a job that drugs tests and is too manually difficult to do while hungover.
