Does Kava Kava increase the power of benzo's. I took kava kava in the morning before school started just a small amount. Then at work I took 2mg of xanax now usually I won't even feel the xanax and have never before but this time I did. I felt a little euphoria and floaty for the first 30 minutes but then just sedation after that. Anyone else have any experience with combining the two? I will try more of this later to see if i get the same results.
