Rock and Roll!!!!
Errr, sorry, I thought this was the Woodstock forum and it needed rekindling.
Concentrate, kava forum, kava forum, kava forum ....
Bert ole boy, I have never experienced that. Now, that being said, I have always been a kava liteweight and I have received all the benefits of kava and effortlessly. My theory is that you become more susceptible to kava as time goes on , not the opposite. I like your bottom of the bag theory. It 's the only thing that make sense to me ... remember ... to me. Try switching to another kava when you get to the bottom of the barrel on the first one and see what that does. Perhaps you need to switch kavas in mid stream to keep your groove going. Or maybe switch in "mid bag". Maybe you become tolerant to that strain over time and you need to switch them around. That doesn't happen to me. I always have 2-3 strains of GHK micronized on tap and I may even do 3 different shells in one day. But I'm not that extravagant, I really do stop when I feel effects and my root lasts longer than most. And when I say "my root lasts longer", I'm talking about kava of course.
P.S.
And for all of you religious fanatics, Kava is not the root of all evil. It's the opposite, evil is the root of not having kava. So put that in your pipe and smoke it.
