I've been vegitarian for about a year and a half and vegan for another year and a half. Recently I've been feeling really dizzy and nauseated. I don't take B12 supplements but I just ordered some. I don't know if I should go see a doctor and ask for blood tests. What should I do I'm scared that I could have anemia and that they'll discourage me from being vegan if something is really wrong with me. Has anyone experiencd this? If so how did it go?
