First of all, good for you for caring about your so and yourself. Sometimes people that have an addiction, can help to stop by replacing it al least temporarily with another "good" addiction. Try to dind something positive that you can do at the same time every night, when you used to drink. Maybe go for a walk and look around at things, listen to the world going on around you. Concentrate on what you would be missing, if you were drunk or sick or worse, not alive. Try reading a good book, or even "The Good Book" the Bible, before you go to bed. Many of the people in the bible went through alot of hard times and found their solutions. Play a game with your son before his bed time, if he lives with you, it will keep you busy and remind you nightly why you don't want to drink. Good luck and God Bless You.
