I don't miss meat at all. In the past I would go a couple of days at a time without eating any before I ever thought of giving it up altogether so no biggie for me. But, I found out 5 years ago that I am allergic to dairy, wheat and gluten. I LOVE DAIRY!!! That was a VERY HARD thing to give up! There are a lot of substitutes out there, soy, almond, coconut milk and many other things but the real thing taste the best to me. Wheat and gluten is very hard to stay away from since it is in more stuff than I ever realized. I can't have it though. :-? I am a real pain if I go to a social function and have to turn down most the food offered. I am not a "food snob" it's just that I can't eat a lot of stuff. I have never ever been a picky eater, even as a child I would try anything. Now it looks like I am picky! I am not picky, my system is "picky"!!! If I give in and have a small portion of what I am not allowed to eat I end up getting sick. Not fun!
On the upside, I have tried so many new foods that are amazing so I am not missing out. It's just hard to go places and a lot of restaurants. Living in Dallas does have it's advantages. They have many veggie restaurants with dairy, wheat/gluten free menus.
