Kava is pretty nasty tasting, but I feel the effects are worth gulping it down. I don't like the extracts and capsules, I think Kava should be used in it's traditional way, by making a strong drink out of it. Depending on dosage, you can feel slight euphoria, to full on drunkenness at high doses. This is kinda random, but if you've ever watched the show "Survivor", they had an episode with Kava in it. It was from the "Vanuatu" season, a lot of Kava comes from the Fiji and Vanuatu islands. One guy drank entirely too much and got pretty smashed. Erowid is the best place to do your research, they have a lot of info on Kava, just search for it.
