Hi, I'm a vegan and about to embark on a grain-free diet as well (hopefully I'll be able to include potatos and rice).
After becoming a vegan 2 years ago, I found I was allergic to meat and dairy. I've had non-stop acne for years, and when I stopped eating wheat my acne disappaited by 25%. I've been reading online that a grain-free diet can get rid of acne in about 2 weeks, so I'm embarking on a vegan grain-free diet for 2-3 weeks.
I am beginning to feel pretty "limited" food wise, but have no other choice since the acne on my face has driven me crazy for 12 years.
Any others who are on this same diet out there? Or am I alone on this mission :P
