Vegan... but... cheese... -drools-
I'm not sure I could stop eating dairy products. I have been thinking about cutting out red meat for a while now, since I don't like it that much anyway. Really, though, I think my problem is that I eat too much chocolate and ice cream.
Regarding vegans and lucid dreaming... I'm not sure if it's the lack of meat that seems to help with awareness, since in cutting out meat you add a lot more fruits and vegetables. A healthy non-vegetarian diet would also include lots of fresh foods. Not eating processed foods seems like it would be a big part of it. It would be interesting to do a study comparing the two.
