has anyone heard of ...

[linzoid]

a herbal remedy called rhodiola rosea? I have heard that it is good for helping you deal with stress and is good for daytime tiredness. Anyone tried it?

I tried it hoping for extra energy but didn't like it. It seemed to make me feel irritable so I threw it away!
Maybe I was just blaming the rr - would be interested to here if it works for you!
