The tea can be pretty potent if you let it steep for a while or if you use two tea bags. I never prepared Kava proper, seemed to much of a hassle. I tried the capsules but they were pretty weak so that's when I switched over to Valerian root. Thankfully, I don't need any of that any more. Got a memory foam mattress topper and all my sleep troubles went away.I didn't know SNS made blankets.... now I want one.
