The effects of drinking kava, in order of sensation, are slight tongue and lip numbing caused by the contraction of the blood vessels in these areas (the lips and skin surrounding may appear unusually pale); mildly talkative and euphoric behavior; calming, sense of well-being, clear thinking; and relaxed muscles. Sleep is often restful and there are no after-effects the next day. In Vanuatu, drinking strong kava is normally followed by a hot meal or tea. Eating after kava often makes it “kick,” causing the effects to be felt for a second or third time. A common bislama phrase to hear in a nakamal is “Kava i kik?” or “Do you feel the kava?” – https://en.wikipedia.org/wiki/Kava
