It depends how much you load into your aluball. I work in grams. Most days, 40 to 55 grams suffices me, but I use other psychoactives as well.
Many people can happily drink up to 100 grams per day, or more, for years, without any necessary, per se, negatives.
Just potential for dermopathy, like a dry, flaky skin condition. I can experience this as a side effect myself, when I keep my consumption higher for a while.
For example, if I keep to 35-40 grams a day, the Dermopathy symptoms settle down.
If I maintain 50 to 60 grams or more per day, I can get very dry, itchy and flaky skin symptoms.
I have never had any skin problems in my life. This is exlusively linked to kava, drawing that line. It comes down ultimately to how you feel. It is important to be in touch with your body, and higher self. If things feel right then it's okay, if something is not right, we should see or feel some signal.
