Welcome. I hope primal works very well for you and your family.
I am borderline Aspergers. Primal has cleared my head a lot.
Vegan works very well at first for people who have been eating a Standard American Junk diet. Eventually, the lack of necessary nutrients from animal products catches up with vegans. As Alicia Silverstone, who I adore, says, you can do "vegan" if you have some fish and other seafood. Mark's wife does that (plus some protein powder.) Some "vegans" feel that it's OK to eat shellfish. This blog by an ex-vegan is worth reading.
