I stopped drinking almost 19 years ago.
I found that I could tolerate less and less alcohol, and the hangovers were getting worse and worse. A pint of beer for example on a Saturday night would see me in bed until 4pm on Sunday. Clearly it wasn’t doing me any good, so I stopped “cold turkey” style.
My overall health improved and for the first few years there were times - especially in the summer - when I did miss being able to have a beer, or at celebrations where the bubbly was flowing but now I don’t miss it at all.
The recent (last 3-5 years) has seen a massive increase in the choice and availability of non alcoholic beers (I refuse point blank to drink chemical laden pop or sugar laden pseudo fruit juices) - which has definitely improved things. There are even some palatable AF wines around too. Round these parts Morrisons seem to have the widest selection of AF beers and wines.
I’m particularly enjoying Adnams Ghost Ship or Speckled Hen AF.
I threw Budweiser zero down the sink, not to my taste!
Technically there are actually few true 100% AF drinks around, but for all intents and purposes I consider less than 0.5% to be AF for me. I can get away with drinking maybe 3 bottles of less than 0.5% beer without any problem..
Good luck to Caroline and OP, hope things work out well.
