Whether you feel more alert or sleepy from kava ingestion depends on your individual biochemistry and also on the product you are using. Often there's a feeling of alertness and stimulation followed by being drowsy and sleepy hours later. Many people have the misconception that kava is a sedative. This herb actually causes alertness, at least initially. The sedation follows many hours later.
