it didnt knock me out nor did i want it to, but i sure did sleep well. this was the first kava i have ever had where i have enjoyed the heavy aspect of kava. i just wanted to chill on the couch and just watch tv. i did not get a sense of euphoria like i do with more heady kavas, but i was very relaxed. i think i might play around with mixing this with moi later to see how that feels.
