I feel like I'm setting myself up to drink later this week. Thoughts?

So I've been sober for 30 days as of tomorrow (after 2 years of nearly daily heavy drinking) and so far have remained sober through my birthday (not something I care about making a big deal of anyway), a few family get togethers, meals out and other small gatherings though I've avoided any nights out and invites to the pub from friends etc (went once with family and tbh I hated it).

So far I haven't really been massively tested and even when the thought of drinking popped up there wasn't a huge deal of temptation on my part I didn't feel like I was ever that close to drinking even if it came into my mind.

I'm going to a concert / gig later this week that's been planned for a while, something I've definitely never been to sober in my adult life before, and I feel like I've started to set myself up for caving into drinking / justifying it.

I've started playing out scenarios in my head that I could drink for "just that one night" or "just have a couple" and then go sober again the next day (or at one point I told myself go sober again the following week!!) and even been mentioning to family and friends that I'm not sure whether I'll drink or not at this gig later in the week.

The friend I'm meeting before the gig (he's not actually going to the show) has said he's happy not to drink in solidarity with me (and he's not a huge or regular drinker these days anyway) and we can just have dinner but I've even messaged him today saying I "might" have a drink or two just this one night.

I'm aware this is quite likely to be delusional thinking that I could drink sensibly or only drink this night and quit again afterwards and that it just sets back my progress.

And sure maybe I could drink this one night and go sober again afterwards but still feels like it would be a setback and a road that I'm probably better not going down YET I'm still thinking about it a lot these past couple of days.

I think the fact I've basically just shut myself away other than family gatherings for the past 4 weeks, not really been going out the house unless 100% neccessary, and not done anything productive or exciting isn't helping either as this feels like an opportunity for some excitement and a release but we all know where that can lead.

I'm guessing this is something anyone who's gone sober has experienced, so...

How did you approach these temptations and deal with these delusional thoughts about it being "one night only" or "just a couple" when that's basically never been the case before?
