yeah, if you do wanna go fully vego or vegan (veg*an) then the bestest way is slowly..One meat at a time, then, if you are morally veg*an, cheese and lollies...etc...But slow is the way to go, you won't feel so deprived then, lol.
And meat subsitutues can help - you can get soy bean bacon for instance, which looks, tastes and smells like meaty bacon (kind of makes you wonder about meat

)
When I first switched I found that those sorts of things really helped.
