Look, it's possible.. I controlled my drinking for years, decades even. I wanted to quit but couldn't because I've got anxiety, and shame. I could make 30 or 60 days.. then I'd go back to it under stress. But I'm super health conscious, and made it a priority to limit myself to 3-4 drinks an evening. Maybe I'm that 'hard drinker', not alcoholic.. who knows? It doesn't matter.
Because you know, at the end of the day, I was stuck anyway - life was passing me by, I was lonely, and I had many failed relationships - because I was self-medicating my emotions. Ultimately, I decided to quit, and when I did I realized much of my life has passed.. while I was *successfully* moderating my alcohol consumption. What a waste. It's so much better now. I hope you don't make the same mistake.
