I've gone through various stages of veganism/vegetarianism in my life. It is really hard to eliminate meat, eggs, and dairy from your diet if you live in the US (I don't know about elsewhere). In most of the country, it is next to impossible to eat out at a restaurant if you are vegetarian, let alone vegan. My mother has been (mostly) vegetarian since the 1970s, but usually made exceptions when going out to a restaurant, simply due to lack of choice. There were also some years where she made exceptions because we couldn't really afford enough groceries to sustain vegetarianism, and my dad hunted, so hunted meat was the exception.

The good news is that it's getting a lot easier, especially in cities. Basically the only things I can't get in vegetarian form are BBQ meats. Everything else has a decent vegetarian alternative. I am hopeful that vegan cheese and eggs make the strides that vegan meats have made, because those are the only things keeping me from going full vegan.
