Draugnar: I don't know :P
I don't even do soda, honestly :P
Apple juice and crisps is as far as I'm going, while I'm actually legally allowed to drink alcohol for another 13 days. Minimum age is 18 in the new year. Not like anyone cares. Most local governments don't even intend to enforce the law.
I don't care about the law though; I just don't see why I would drink.
My pilosophy is quite simple: when I really need something to cheer me up some day, I can always try a soda, since I've pretty much never had it before. If that doesn't cheer me up, I can try eating more than healthy. If that doesn't work, I can try some alcohol. If that doesn't work, well, then I'm in serious shit already :P
I like my life and I don't feel the need to try less healthy stuff, because, what good can come from it when I like it more than what I'm eating/drinking now? It will become normal soon enough, but that doesn't make it less unhealthy.
