Hiya

I'm veggo, was veganish for a while there, at the moment my diet sucks though (just being super lazy and eating junk )

I went (pardon the pun) cold turkey with meat. It took ages for me to make the final decision not to eat meat... I always knew it was something I wanted to do, was just a matter of actually doing it. I was veganish for a while (I called it 'vegan at home' lol creative, I know.) just because it was too hard to be vegan all the time.

I've kinda got it easy because it's just me, I can just not cook what I don't want to eat. My suggestion would be to start small by increasing the veggies & grains you do eat now, and start cutting back on meat. Have a few 'meat free' days, dabble with it. Google recipes, try them, figure out what you like. I personally don't like meat substitutes... I just use beans & legumes in the place of meat in my 'meat' dishes (eg burritos).

As long as you make sure you are eating a varied diet you shouldn't have much to worry about wrt vitamins etc. You can get a vegan multivitamin if you're worried.

Alicia Silverstone's book 'the kind diet' is pretty good, nice amount if information without being overwhelming. There are plenty of brilliant sites around too if you just google away.

I'm sure more of the vegans/vegetarians will pop in here and help you out there's a few threads in the vegetarian recipe section too that might help.
