Query: Does not work for me.

It didn't work for me, at all. No noticeable effects what so ever. I took 2 on my first day, then 4 the next, then 8 the next. I took 8 for the next few days and still nothing...If you are looking for a Kava product from which you can actually feel the effects, this is NOT it.
