I quit around the same time as OP, cold turkey from probably 24-30 units/week. My BP was high, so I cut out alcohol and salt. I can’t say that I really identify with all of the sobriety is so great proponents, but it’s aight. My BP is under control, I’ve lost about 15 lbs. now, and I’m not ingesting poison to quell anxiety any more. Anxiety generated by drinking to quell that little bit of anxiety – see books below.
I did notice a significant difference in anxiety level, especially on a business trip like two weeks in. So normally on this type of trip, I would have 5-6 beers every night, go around to the craft beer bars, and be dragging a little in the morning. I had a big presentation at 8 am, and normally the night before, I would be like, ok, I have to keep it to 3-4 beers, get to bed early, and that would provoke anxiety. This time, I was struggling with cravings, and so I ordered food and kombucha for delivery instead of going out for dinner. Went to bed at a normal hour, and nailed the presentation with very little anxiety. It was very nice not to show up with bloodshot eyes, unable to concentrate, and wondering whether it’s completely obvious that this drunk was out drinking all night, and can barely function. That was a huge difference, but one that I would call being normal, not like some amazing experience of sobriety. Before, I was stunting and dulling myself, and now I’m not.
I think I posted in the yearly goals/resolution thread some resources for quitting or just exploring. I found the Reddit sub /r/stopdrinking to be invaluable. Reading about experiences similar to mine, and making recommendations to people in similar situations was really helpful. Two of the books they recommend are excellent: Grace, Annie - This Naked Mind and Porter, William - Alcohol Explained. If you are thinking about quitting, but don’t know whether you really want to (but I like alcohol), these are good books to read while you are still drinking and making your decision. I feel like I missed out a bit by not reading Grace’s book (and her 30-day test experience on her web site) before quitting.
BTW, my go-to replacement drinks are NA beer (Athletica Brewing lately), kombucha (homemade or store-bought), and seltzer with a splash of juice (usually grapefruit).
