I know it is difficult to get rid of an addiction as I was once addicted to cigarettes, however with the Lord's help everything is possible !
Every time you feel like doing anything you should not, open your Bible, read some, and pray.
I Peter 5:8 says:"Be alert and of sober mind. Your enemy the devil prowls around like a roaring lion looking for someone to devour."
Please, don't allow him to.
Psalm 27:14 "Wait patiently for the LORD. Be brave and courageous. Yes, wait patiently for the LORD."
Yes, pray incessantly. Ask someone whom you can trust to meet with you and together in "prayer and petition" let the Lord know your weakness, humbly ask for help and strength. He is the only One who can everything, and with Him you can as well.
God bless !!!
