Yes. Went from omnivore to vegan overnight, stayed that way for two years, and then went vegetarian three years ago. No meat since Jan. 3rd 2012. When my wife and I took the plunge I had been eating lots of meat at lunches...mostly in sandwich form and we had been unintentionally transitioning from all meat to chicken and fish to mostly just fish at home for dinners...wife's preference for fish over other meat drove that. Then we watched the documentary "Forks Over Knives" and, regardless of the scientific accuracy of the film, said "Why don't we try going vegan for a month and see what happens". So after a New Years trip to see family in LA where we are a ton of meat we drove home and then...never ate meat again. After the first month "test" we asked each other if we should try it again for another month, agreed to do it, and then never asked again. Over the holiday break in 2014 we ended up eating a bunch of eggs and decided we really wanted eggs and cheese, so we ditched the veganism and went vegetarian. We probably eat 80% of our dinners as vegan still, unintentionally, but we don't feel bad about eating cheese anymore. One quick tip if you try to be vegan...be flexible if your not doing it from a moral standpoint. If I ordered a sandwich and they accidentally put mayo on it, I just ate it anyway. If a coworker brought cookies or cake, I ate it. I didn't ditch my shoes or belt. True vegans would probably be appalled, but life is so much easier if you go with the flow. Try to stick to it, but don't fuss or worry about the occasional lapse. Hell, I know plenty of vegetarians that are 99.9% vegetarian but occassionally grab a slice of pepperoni pizza or slice of bacon or whatever. There aren't any rules...it's a personal decision. Do what makes you happy.
