I am on the 4th kava I have tried because I see the potential. I have anxiety bad, which is my main reason for using kava. I just bought a kalm with kava boronguru, as I understood it is supposed to be heavier and less heady, good for anxiety. I tried two tbsp last night. It was a subtle feeling, but definitely what I was looking for. This morning I woke and was feeling more nervous and nauseous than usual. But that happens to me sometimes regardless. I decided to try the full recommended dose (on the bag) this time and used 4 tbsp. So for the first 3/4 of the cup I drank out of I felt pretty good. I was in starting to feel a little antsy in my chest. Then I took the last bit and -clink-, it's like it instantly bonded with the other kava and I felt like I had taken an amphetamine. How subtle is kava supposed to be, because I hear all different accounts of it's effects on people, and does this sound like I took too much and should just be happy with the very subtle feeling?
