I've been experiencing some nausea lately and have been going easy on the kava drinking. I think I'm going to try eating a small snack/meal beforehand and see if that helps.
I really like the GHK Papa Kea. I made strong grogs and medium strength grogs with it, and have found that less is more with this potent kava. It is a serious anxiety buster and mind/body relaxant.
The 20g Kava Kwik sample that I received from Kava Kauai/RealKava was just enough for me to be sure that I'll be ordering this instant kava again in a bigger size. IMO, its heady and heavy effects were quite pronounced. I definitely felt an uplifting calm come over me while drinking. All was well in life. I started off with 1tsp, but found the sweet spot at 2.5-3tsp per drink.
