Actually joined this forum to discuss this specific herb and effect. I suffer from quite specific (kind of performance) anxiety, and in particular for a job interview I have soon.
Today tried taking a few Kalms (main ingrediant valerian) - maybe just the placebo, not sure, but I was feeling really anxious (got a confirmed time for interview today that set me off), but after taking a couple of these valerian based things I do actually feel a lot better. Feeling kind of vaguely happy (bit like a small stoned feeling) almost want to grin a little....
Just hope my experience might add to the previous views for this one - I've just ordered some plain valerian tabs too, will try those out as well.
