I'm completely vegan, no dairy, or eggs at all, and I don't eat tofu or seitan. I'm struggling with headaches and finding things to keep me full. Any advice? Does anyone know of any vegan brands of butter, or meat replacements that would be compliant. Been on the diet 3 days and haven't stopped being hungry yet, and feeling very lightheaded and weak. I can't work like this, but I don't want to give up the diet because I'm doing it with a non vegan friend and I want to be supportive. Please help.
