18th Birthday, first time drinking. Drank 4 pints of weak beer, didn't get much out of it; thought 'this can't be what people drink for.' - friend cracks out a bottle of 60% absinthe, and I nailed back what would've been like 8-9 shots worth (disgusting). Still didn't feel anything, continued drinking beer for about 20 mins. Then I stood up and shit it all hit me at once. Weirdly I didn't get sick, but it wasn't nice - just confusing and grim.
I didn't drink for about 3 years after that, I just thought there was no middle ground with it, it either didn't effect me or it felt nauseating.
Then I got into lunch-time beers at uni; Loved em! Don't know what changed but I could appreciate the small buzz a lot more, plus I loved the vibe of chill drinks with friends.
Problem with drinking though is why you do it. See I tend to stress out about small shit a lot, and for a long time drinking was an answer to that problem. My tolerance built, I drank more frequently. And before long it was just a habit. Like I'd be sitting down to watch a movie (this isn't as good without a drink), I'd go out with friends (this isn't as good without a drink), fuck... just sitting on the couch was fun if I had a small buzz going.
I never got any health problems from drinking because relative to some people I didn't drink that much, but I curbed it in my mid 20's and it felt like a good move. I still drink with friends, but I don't plan it out, I probably drink once a week if that and then it's only like a pint or two.
Advice is: if you can do without do without, it fucks some people up. If you like having a beer though, that's cool, just don't make a habit of it.
