You've got the right attitude - its an investment in yourself that your future self with benefit from. Good luck on your journey.

Edit: Apologies for the novel, might've gotten a bit carried away.

I dunno your lifestyle around alcohol, but if you really enjoy your beer for the beer of it all (and it's not a problematic habit/drinking purely for effect), moderation and mindful nursing might be the move. Take the stuff below if it makes sense when being radically honest with yourself, toss it out the window entirely if it doesn't.

Set one night a week (or longer interval) as beer night. Pay attention to what us other substance freaks call set and setting - go into it in an already good mood, in a space and set of circumstances that are arranged to be pleasing (for me, that's out at a place I enjoy, preferably with something I like going on [live music, etc.]). If the set or setting (or, to quote Gen Z, the 'vibes') are off, do it some other time.

If the vibes are right, order/get one really, really good beer and a water. Your goal is to make that beer last at least an hour - you can have as much water as you want. So obviously, you should pick a beer that doesn't taste like ass as it comes to room temp.

Take each sip very slowly - sniff it before you sip, let the beer sit on your tongue a bit, with a breath through the nose during, and sit with the finish after you sip for a little. Keep the ratio of beer sips to water sips at like 1 for every 4 or 5. Just make a mental note of stuff like the flavour, texture, finish as you're drinking. Make note of any changes to those over the interval.

Once the beer is finished, have something else (preferably lower sugar - soda water with a little bitters and lime, hop water with a hop profile you enjoy, whatever you'd like from what's available. If out, ask the bartender for a suggestion, some like the challenge but be mindful of how busy it is). You don't need to make that last an hour, but try to enjoy it slowly. Once that's finished, decide if you want one more beer, and if so repeat the process. End at max two beers, though you can close the tab (if your ideal setting is out at some place) on a not-beer-not-water drink if you want to stretch out your time in the atmosphere.

Life's short, and filled with both horrors and moments of bliss. Little pleasures can enrich your time here, so long as you're careful not to let their fingers wrap around your neck and become vices. Just have to approach them carefully with an eye to your larger goals and ideals.

Or, if you look at this and think "Naw dawg, if I tried this it'll end in chugging multiple beers", ok, let the beer go. There's myriad other little pleasures you can integrate into your life, many of which are healthier anyway.

Edit edit: if you take the approach above and your ideal setting is out at some place, I usually follow a $1 per drink tip rule, and that calculation includes the water. It ingratiates you to the bar staff who might otherwise be peeved you sat there for two-three hours. I call it vibe insurance, lol.

If gamification works for you, maybe give walkscape.app a chance. Looks cool, but my phone was too crappy
