Experiences with the No Grain Diet As advocated by Dr. Joseph Mercola?

I am interested in anyone’s experiences with this Diet – Good or Bad.

What made you go on this diet?
Was it difficult?
Did you lose weight? Was this even a motivating factor?
How did you feel?
Repercussions on your digestive system and other health systems?
Are you still on it?
How strict were you?
Has it had a mental or spiritual affect on you?
Etc…
