If anyone has any kind of addiction, please get professional help and support. Also it is a great benefit when one can open up to a supportive spouse, loved one, minister or friend. There is no quick fix. All denial, excuses and lying must stop. There needs to be a clear plan of action and self-discipline to follow through.
Prayer helps too.
There are excellent rehabilitation clinics and ministries that offer free counseling to people of any faith for all kinds of addictions. There are excellent books and Web sites giving expert advice and guidance. Every bit of right knowledge and motivation will help. The Scriptures are a valuable source of right perspective, personal strength and inspiration. Most are familiar with the account of King David and Bathsheba.
