-the taste
-the fact that kava is not very reliable (at last for me): sometimes it is amazingly divine and then the next day it is frustratingly boring
-the prerequisite empty stomach
-eating food kills the kava effects
-I wish we could eat the leaves: it looks so yummy
-last point, I just wish there would be a lot of kava enthusiasts growing it as a hobby and we would be exchanging growing tip and cuttings, comparing homegrown kavas etc...I am a gardener at heart
I don't really care for dermopathy because i usually make a long pause in my kava drinking when it happens, I use kava in cycles...
