I notice that some strains make me pee a bit more than others, but not only that some experiences make will make me urinate significantly more than others, even though it's the same root. For the most part, it doesn't behave like a drastic diuretic to me, but I notice others differences too sometimes....like, not peeing as much as the urge made me assume or peeing and having to pee again a bit too soon after. Not sure if this is natural, or sign of an underlying health issue. I definitely notice that the nights the really hit me the best, will definitely have a period of somewhat notable increased urination...followed by a foggier next-day than usual.
For me, alcohol makes me pee much more volume, more frequently, than kava usually does.
