from what I understand it doesn't....
Alot of people don't use kava every single day, like myself...
I tend to use it like 5 days out of a 7 day week. but it all depends...
Once you finally break through the reverse tolorence of kava, I don't
think you will ever loose it!

From my experience even taken 3-4 days of just makes the
next time I use kava all the more meaningful and effects seem to get stronger if I take few days off...
But Im still fairly new here so I, like you are just getting my feet wet!

glad to have you aboard!
