Rookie, here is another factoid. People react to the same Kava in different ways. The only way to know for sure is to test it yourself. I have tried playing the numbers games with Chemotypes but it is not accurate. As I keep getting reminded, there are 6 major kavalactones but a buttload of other kavalactones and enzymes that provide the total package. I will be downing some Nene in about 1.5 hours so I can sleep like the dead. Except for the dead part.
Ya know, it might even be "all in my mind" but it works for me so why fight it.
