Valerian Root-when to take?

Hiya-
I'm getting dizziness and general unsteadiness and a heavy head every day now and it is beginning to affect my life again. I take prozac, fish oils and vitamin B complex daily but i was thinking about taking valerian root too. I have bought some and it says to take 2 at night but i would really like to take it during the day as this is when i am feeling at my worst. Does anybody know if this is advisable?
Thank a lot

Also, ive just read another post and it says not to take valerian with SSRI's so now im slightly scared! lol

Valerian is used to help you sleep hence should be taken at night. I take it sometimes.

I am not sure about the interaction with SSRI's.
