I'd suggest being careful about putting any substance, on a regular basis between your mind and dealing with reality.
I have taken Kava Kava in the past for anxiety, before I got clean. I've also read about the way it is used in it's own culture..there are Kava Kava bars where people go in the evenings, do Kava and stumble home afterwards....
just something to think about...it may make the Polynesians happy, the same way a lot of hippies were happy.
I know anxiety is a real issue. I have it myself, and have suffered from debilitating panic, it's one of the worst things in the world and led to me using to escape it...but Kava Kava, natural or not, and Valerian..in the hands of an addict like me...are one more way to use.
