I'm a vata too, so part of your message struck me. I know I have seen Andreas mention in the past that once all your doshas are balenced, the body would instinctively know what to eat... so then just follow your guide when you reach that point. I have also seen him say that when people are very unbalenced, their true dosha may be hidden until cleansing helps clear things up. not sure how that affects you.
re the vata diet... the diet Andreas recommends for each type appears to me to equally healthy, that is optimally suited to that particular type... so i'm not sure what bothers you about the vata diet as opposed to pitta and kapha? its not like the vata diet is chocolate and beer... (i wish).
