So I am freaking out a bit about my lack of self control. I was vegan for two years before getting pregnant in June and I never craved cheese or animal products until now. I am 12 weeks pregnant. I had awful nausea and vomiting for many weeks early in pregnancy but since last week my appetite is back and I've been craving and eating cheese! I don't even feel guilty even though normally eating animal products would horrify me. I've eaten either pizza or cheese on toast every day for the last 4 days. I feel quite disgusted with myself but am trying to tell myself it's just a temporary pregnancy thing! I'm not overweight (BMI 18).
