I don't understand why people talk about giving up alcohol for one month like it's a big deal, unless they actually do have an alcohol problem and find giving it up a struggle (in which case absolutely talk about it, get support, and let people motivate you with their encouragement).
I almost never drink. Not because of health risks or some kind of moral high ground, but because I have a wildly unpredictable reaction to alcohol - I could drink a bottle of wine in one sitting one week and barely feel any effects, then the next week a single glass would have me blind drunk and hugging the toilet.
It meant going out for a polite social daytime drink or having a little glass of something when my kids were in bed was a gamble, so I just stopped.
No moral judgement, no high horse, just someone who doesn't want to accidentally get pissed after a small glass of sauvignon at 1pm on a Tuesday afternoon, have to go home after a couple of pints on a night out, or get up with the kids while battling a headache sent from the devil himself because she recklessly decided to have a wild night (a glass and a half of prosecco).
When someone's buying a round and I ask for a soft drink, they often think I'm being polite and insist. It surprises me how often, when I say that I don't drink, people assume that I'm judging them and become apologetic or defensive.
I'd kind of like if it was more accepted that some people just don't drink, without the automatic assumption that they're either an ex-alcoholic, or about to set up a PowerPoint in the middle of the pub to deliver a lecture on your liver.
