I've been a vegetarian since conception*; I just don't like meat. Even as a baby I would spit it out. But I do eat chicken soup, for some reason.
But it can be tough being a vegetarian, especially if (like me) you don't like certain vegetables. It's even worse here in the USA; I haven't seen one purely vegetarian restaurant in the last nine months.
If you want reasons to remain a vegemetarian, read
http://en.wikipedia.org/wiki/Vegetarianism#Motivation. The one I find particularly convincing is that it is incredibly inefficient to produce meat; it takes at least four times as much energy to produce a pound of meat than a pound of grain (and that statistic can go up to as much as 54 times).

My mother had anti-cravings for meat when she was pregnant with me and my sister, who is also a vegetarian. But with my brother she had cravings for meat and he's a huge carnivore. Which begs the question; did her natal cravings affect our tastes or did our biologically-programmed tastes affect her during pregnancy?
