That's one hell of a range ! I usually have 2 tbsp before dinner and then 2 tbsp a couple hours after dinner, sometimes I might have 1-2 more tbsp just to set me over the edge. I'm very kavain sensitive so if I do much more than 6 tbsp I will be out of my gord with nervous energy. On average it's 4 tbsp in one evening total. Tonight before dinner I had 2 tbsp Hiwa, and now I just finished 2 more tbsps Dua Na Bilo. After the second wash I just don't think I need much more. BULA!
