Going Vegan: Newbie!!!?

Ok so after watching a very disturbing video about animals, I just can not see how people could eat meat. Trust me I was an avid meat eater so I am not downing the rest of you but for me I just can't support it. Anyway after I watched the film they asked me if I would go 30 as a vegetarian, which I have done before, but I thought to myself why not do it to its full capacity. No milk, eggs, bread, etc. So now this is my first time and I hope last, that I will be a vegan. My concerns are: the food will be very repetitive, and expensive, but hey I'm still gonna do it. For the vegans out there: 1. Where can I buy vegan products ( I live in NYC) . 2. Are they good? Haha I had to ask. Any tips or advice! Thanks everyone for any feedback. After 30 days I will see how it goes but I hope to continue this lifestyle. P.S. Starting today: Meals for the day oatmeal with water, veggie stew for lunch/dinner, and fries for snack! Doin ok so far >? THANKS!!!
