Going to try it this weekend, I enjoy that sedated feeling in the afternoon so I can take a nap. I have sleep problems where I get up at 2 o clock in the morning and can't fall a sleep.
Valerian is a mild Central Nervous System depressant, so care should be taken when combining it with other CNS depressants, but you shouldn't have anything to worry about. Have a good time and don't overdo on the Clonazepam (Klonopin, Rivotril)
