Finding other sober students? Good idea?

Essentially, I have applied to a couple universities and am now on Facebook groups for applicants. I want to get to know people and, from last year, I'm familiar with the fact that course and accommodation chats get made.

However, as much as I'd like to know potential coursemates and other first years, I don't relate much to topics of conversation. Already, people are talking of 'seshes' and drinking and all that sort of stuff which is really not my thing. I'm a rather reserved person (and have had CBT for social anxiety) and I don't drink. I know from my time at uni this past year, before dropping out due to my mental health, that I just end up having panic attacks so those sort of things just don't work as a social event for me, especially without anyone I'm comfortable with already.

So, in short, is it weird to ask on the Facebook groups if there's anyone else who doesn't drink/prefers not to party?

I just think it might help reassure me I can get through uni this time if I know there are people who are going to be okay socialising in different contexts like I do. But I also worry it may make me come across as pretentious/boring/childish to the (most likely majority) who do like a drink + a party.

The only thing I would caution is do you want to give so much information away before people meet you. There will be plenty non drinkers there in reality. If you do post make it positive. Look for people who share your interests perhaps rather than other socially anxious people. More than 1/4 of students do not drink according to stats.

What would you say constitutes as too much info? I'm not exactly planning on giving everyone my mental health history and seeing who's the exact same lmao - if I can I'd rather leave my mental health out of these conversations w/ the people I may end up studying/living with because I know there's a risk some of them will write me off for it.

And, I know about the stats but, like I've said, I also know from experience at uni that it's hard to find the non-drinkers (and, yes, I admit covid had a part in that because the restrictions at the uni meant socialising in lessons or at societies was pretty much just impossible where I was so the only meeting opportunities were at parties hosted by students in their flats but it's still uncertain how much more in-person things will be able to officially be next year).

Like, a lot of people get invited places and hang out at parties - those are the things that get put on the big group chats for people to attend (based on my experience) and everyone who doesn't like that, doesn't get those open, easy invites to social occasions in those early weeks. And, I just wanna see if I can find people who also don't like that so we can have a group to like host things that we're more comfortable with to try and make friends in those early weeks? Y'know before (hopefully, covid-permitting) we start making friends at society meetings and in class and so on?

So yeah, like what would you say is too much info? And how would you make a post positive?
