Oh Damn! I'm another victim of Kona Kava Farm!
I've been using Maeng Da K@ before work, in small amounts: dismisses my tiredness and aches and pains so I can work my evening job. Cuz I'm getting old! I've been using kanna on my days off from K@. I found this German company that makes "energy snuff" and mentholated powder "snuff." I mix it in with finely ground kanna and snort it. Privately of course, I don't want to have to explain "no, it's not cocaine, it's legal!" Blue Lotus is incredibly subtle and not much use unless combined with alcohol-- although soon I'll try with kava!
