so in the last 6 months my food had gotten progressively more vegetarian and less vegan. ive gained about 10 pounds because of it and i am mad at myself about it. i want to go back to being 100 percent vegan.... cheese doesnt even taste that good anymore its mostly egg whites that i crave.

Don't beat yourself up too much. If you are craving egg whites, maybe you aren't eating enough protein rich foods. What are you eating?

I agree with nelie, it sounds like you are missing something in your diet.
