Ok, so I have to write more here. I just experienced my first truly pleasant effects from Kava. But it is too fleeting. This is really strange stuff. For a few minutes, I had on/off feelings of strong euphoria and a very pleasant body feeling, very very nice. Altogether, that lasted in on/off mode for about 20 minutes. This was actually the first time that made me want to continue experimenting with Kava. Maybe my switch of prep method paid off. I'm heading to the kitchen to make a 2nd 2 tbsps. batch of Boroguru.
Oh, I have to add, I don't know, I am not sure at all that this is reverse tolerance. I think it is something else, like a learning, an acquired taste, not sure. But I'm not sure about calling this reverse tolerance since I have been feeling this stuff since batch one, just that I was strangely indifferent to the effect and found no pleasure in it.
