Hi and welcome
nearing 30 I am asking myself cant I just go out with my friends like an adult and have a drink, go home, and wake up and go to work?
I'm not sure anyone can answer your question, but I can share my experience.
I've been addicted to many many things - the problem wasn't actually the drugs and things themselves, the problem was me.
If I was you I'd want to be really sure - REALLY sure - that alcohol wasn't going to lead you to the same place crack did.
You've been clean and sober for 8 years now, right? good life, no problems more than any other guy?
Sure you might be a normal guy who did some stupid stuff in his youth.
You could also be someone who's addictions been waiting patiently for 8 years to get you at a weak moment.
Honestly, my advice? I'd err on the side of caution.
You're not missing anything by not drinking, man.
