Welcome to SR Achilleys.
I have a list of things that are good about not drinking and things that are bad about not drinking and as long as the good outweighs the bad I will not drink. If I am struggling I read the list carefully.
My relationship with my family is the first thing on the list by the way and that alone is enough reason for me not to drink.
I also wrote a letter to my wife promising not to drink and I try to read this weekly in order to remember what got me to where I am.
Good luck to you.
