I'm nearing my 30's and I only started a year ago. Was always scared about drinking due to a bad experience I had with it when I was 15, but my career went crazy and I got to travel around the world giving interviews and demoing my work, and everyone around me would be drinking something.
Maybe because of being a late bloomer I have a different experience to its effects. I find it very good at getting me to focus on something I normally wouldn't like (people I don't connect with, boring films etc), it makes me wake up extremely positive and I only need a couple of hours sleep if I've been drinking, it makes me work really fast. Never had a hangover.
It's not much though: I'll have 3-5 small whisky shots in a session, or a couple of glasses of wine. Once every 2 weeks.
