Has anyone gone vegan without transitioning? It's been just over a week. I was eating meat and dairy before that. I eat raw veggies and little processed vegan food. I even cut out sugar and now I'm only consuming organic sugar if necessary. I'm tracking my food and reading all ingredients. I don't think it's a problem of not getting enough protein or anything. I have the worst headache and after I eat like an hour after I can't move because I'll vomit. This is the last three days. It's gotten abit better. But I'm wondering what other side effects people who went straight vegan have had? Thanks!
