Yesterday evening I had about 30 g of instant Kava. I woke up very tired in the morning. I went into work and nearly fell asleep (even after drinking a red bull). I drove home and took two naps during the day. It's nearly 4:30 and I still feel like I just woke up. This is very uncharacteristic for me, and frankly, it is scaring me quite a bit. I never have issues with lack of energy motivation. I've had Kava before, and drank just as much the day before. Can Kava do this?
