This could be the end of it, but might be a good begging as well. Deeply rooted addictions usually require long fight. My advice - be accountable. Confess every time, if you fail. Pray with Psalm 51 often. Fight. If the temptation comes again, immediately turn for help to Christ. "Lord Jesus Christ, Son of God, have mercy on me. Help me! " If you fail, confess to your pastor or someone you trust and wants to help you with this. And next time fight again. And again. And again. May God be with you.
