I'm a big time clubber/raver, I really love that kind of lifestyle... tho' I don't drink at all. I go to the clubs/events for a quality music (electronic usualy), that's the best drug I've ever tried (not that I tried many, anyway). Nothing better then a "natural high", no downsides to it. Having a crowd of people who are the same - helps.
Great music, an early morning, a sunrise, the "afterparty glow", a nice feeling of tiredness, the feeling of another great night out - all this wouldn't be possible if one'd get drunk (and drinking just a lil' usualy drains the energy to some extent too. It's just not the same..).
I could do other drugs, but I chose not to.
Having a great time without getting fucked up is entirely possible, I'd say - it's a lot better if you learn to relax without the help of some shit..
