There is a man, Matt Talbot, who is being examined for canonisation. He was a practicing alcoholic who got sober through the grace of God and dedicated himself to Eucharistic Adoration until his death. My suggestion would be to pray for his cannonization and for his intercession.
Prayer for the Canonisation of Matt Talbot:
Lord, in your servant, Matt Talbot, you have given us a wonderful example of triumph over addiction, of devotion to duty and of lifelong reverence for the Most Holy Sacrament. may his life of prayer and penance give us courage to take up our crosses and follow in the footsteps of Our Lord and Saviour, Jesus Christ. Father, if it be your will that your beloved servant should be glorified by your Church, make known by your heavenly favours the power he enjoys in your sight. We ask this through the same Jesus Christ Our Lord, Amen.
Also, does your Parish offer a Crown Ministries course? Mine does and it has been tremendously helpful to people stuggling with money addiction.
