I'm never over the limit if I know I'll be driving.
I can have 1 beer in a bar , finish it , immediately get up and go home. If I have a 2nd one, I'm afraid I'll be there all night.
I was drunk from age 18 to 22, 24-7. Even married my bartender ( First wife), man, she made the best Tom Collins ever....I kinda miss that.
Was dry for 25 years. I allow myself only one these days , hasn't become a problem.
Restraint hasn't been easy, but it has been worth it.
