DrSober, you are on the money as far as I'm concerned.
This is my 4th time getting sober. I've always done it for everyone else but me because the thought of never drinking again frightened me greatly. It took me this 4th time to realize that I'm sick of it, that it's time. To help with the frightening part of it I make no promises that I am not going to drink in the future, but I will not drink today. That's the way that it's been for the past 45 days. Seems to be working!
On the day that I quit, unbeknownst to me, my husband was filing for divorce because I had gotten drunk and bad mouthed him for the last time. By the grace of God I made the decision prior to him going.
Like you, I quit for me but keeping my husband in my life is a key motivational factor.
Kudos to you!
