Nature's Resource Valerian, 400mg Active, Capsules - 100 ea

Yes, I have to agree with everyone else here, these pills smell absolutely horrid, but I tried them last night, and I did get a noticably better sleep, I just felt more refreshed.

Update: I've been taking two a night, as the bottle suggests, and I am getting a more rested sleep. It's been a week now, and I don't really notice the smell of the pills now either. Good stuff. Celestial Seasons also makes a tea with Valerian, so if you don't like pills, perhaps try that.
