Alex L.:
Yes I drink a lot of green tea which I believe supposedly has the L-theanine you refer to.
I should mention that that my longest and best mediations usually happen in the early morning before I've has anything. But I think that just reflects when I can sit as everyone's asleep.
Anyway I'm enjoying low carb clarity most days and the coffee definitely helps me function in life
thanks for sharing your experience. I will look into PQQ
I, too, have been following a "paleo" (so-called) diet. It is truly amazing the difference in mental clarity. I have always been hypoglycemic/borderline diabetic, and the reduction in carbohydrate from drastically cutting back on cereal grains and beans has made a huge difference for the better.
I definately want to try the BP coffee. Thanks for the heads up and to others for the links.
