Havent RTFT.
As a former lush, a bottle of Prosecco would have gone down like a pitcher of Ribena for me. I don't drink at all anymore because I'm incredibly sensitive to alcohol now.
I'm interested in the fact that OP is considering doing dry January until Easter and that she said that the comments saying that a bottle of Prosecco is fine were making her 'feel better'.
Personally, having spent decades on my life drinking excessively and now being a teetotaller, I see alcohol in way that maybe social/habitual drinkers don't. Maybe I'm biased.
But if you are planning to give something up, that suggests that deep down you knownits not good for you. If you're reaching out to see how much other people consume and feel relieved when they drink the same as you, that tells me there is some kind of internal stirring.
For years and years I questioned my drinking, the frequency and volume of alcohol I was taking. There was always somebody saying 'don't be silly, it's totally normal! I drink the same!'. That would set my mind at ease until the next time I felt ill at ease and wonder if something was wrong, if I should cut down.
I said on a previous post about alcohol, not to look to the culture to tell you if your own personal relationship with alcohol is problematic. Everyone around you will tell you its fine, even if it's not. If YOU are questioning whether you are drinking too much, if YOU have some deep niggles about whether your relationship with alcohol is problematic, if YOU feel it is affecting your life in some way, listen to that instead.
Maybe I'm way off the mark, maybe I'm reading into things where there is nothing there, but it's always good to truly question these things if there's any doubt. A lot of people are caught in a trap of drinking too much and don't realise they are in bondage to it themselves.
Some people can have a couple of glasses once a week, it's all good, not an issue, no consequences, etc. That's fine! But some people don't and sometimes don't know what voice to listen to. I say listen to the voice that YOU have to live with.
