Does anybody have experience taking valerian root in the daytime?

I take two every night as a sleep's basically the one and only thing that can get me to sleep properly, and not be groggy the next day.

Lately I have been contemplating taking one at a time, once or twice a day during waking hours. I know it's supposed to help as an anti-anxiety aid, but I've never used it as such. I've been getting really, REALLY bad anxiety lately, like to the point where I feel panicky and can't breathe or function really, and I need to do something about it because this is just not working for me.

Thoughts? Any other suggestions for natural anxiety remedies? Thank you in advance for your help.
