Decided to quit drinking for good - no excuses this time

Decided to share my path and decision with the rest and get it out of my chest. Long story short, I was never someone who cannot live without a drink. Usually the only time I was drinking was when I go out with friends. But for the past like 3-4 years when I am out with friends I literally drink till I blackout without much control over me, doing stupid things, talking stupid stuff to friends and people around me. I was always like talking to my self yes this will never happen again etc but so it happened again and I decided no more alcohol for life. My drinking is rare like such blackouts happen 1-2 times per year but still the anxiety the next day is literally so overwhelming that I am to a point of am I normal what is happening to me. I am genuinely a nice person like decent job, great family but this drinking is for real destroying me. So from now on no more drinking. Can someone who was in my shoes help me with the mindset. Literally yesterday I got so drunk that I blacked out so today is my 1st day where I make this promise that I will quit for good. How do you guys fight the anxiety the next day... thinking omg what I did..
