If drugs & alcohol have more control than you do, have faith first and foremost that YOU are in control. I read here last night that one person asked himself a question "Is it really worth it?" and he stopped cold turkey 7 1/2 years ago with no other intervention other than his own honesty with himself.
Here's how I did it. I woke up one morning getting ready to go buy more booze because I was out and I decided I'd had enough of paying 400$ a month for the right to poison myself so I stood in the middle of my living room and prayed almost in a shout:
"Demons who inhabit my space and cling to me, be gone in the name of God and of his Son Jesus Christ. I will no longer be tempted by your sickness that tortures me. In the name of Jesus Christ I am protected BY GOD from you. Be gone and never come back."
I prayed this several times a day, mainly on my knees, and stopped boozing and doping. It wasn't easy, but I knew that God was always there for me and that prayers banished the temptation/demons.
The lie of the victimhood culture is that you don't control your life and your spirit. I'm here to tell you that through Christ you EXACTLY have control of what you put in your body and what you give your spirit.
DON'T LET THEM LIE TO YOU. You, through God, are the strongest soul in the universe. This is YOUR TIME as ordained by God. You can do it. Millions, including me, are PRAYING for you to do it.
The only thing left is for you to do it and God is one prayer away BEGGING to help you. Stop the booze. Stop the drugs. Replace them with God and with things that serve you.
God bless these words and bless the souls that partake in them for healing. Amen
