I am catholic, too, but I usually don't give anything up for Lent. I am also a vegetarian for almost 15 years now and I believe that my lifestyle justifies that. However, two or three years ago I decided not to eat any sweets for Lent and I really managed it. I remember that it was quite hard. And everything tasted way too sweet afterwards when I started to eat that stuff again, so it's probably not a bad idea to give the things up that aren't good for you in the first place. But since I barely eat more than three cookies every second day, I don't feel the need to give sweets up this year. So I basically live as usual.
