All good advice above. I'm coming up to a year without alcohol, and have had great support from the threads on here.
I started by trying to go for 30 days, using the online (and free) Annie Grace Alcohol Experiment and reading the Allen Carr book. Once the thirty days were up, I was on such a high that I didn't want to go back to day 1. Having said that, I'd had a couple of unsuccessful attempts last summer, but wasn't really in the right headspace at that time. What changed for me was realising that I could not cut down, I had to give up alcohol entirely.
I still use a daily mood tracker app (Daylio, it's free), to count the number of days, but it really is just a number, and I don't think about drinking at all.
My life is just so much better now. I no longer have anxiety, I sleep better, my rosacea has disappeared and I have so much more time and motivation.
Best of luck, you really won't regret it, as you are giving nothing up, you are getting your life back.
