I"ve noticed that the duration of effect from one Kava to the next is more drastic than I thought.... So in that light I was wonderring what you guys have found to be the longer acting and shorter acting varieties from N@H...... In particular the information I'm after now is which Kava's will wear off before work the next day in taken at the prior night. Thus far I've found that: WoW! Stone, and Solomons definately last a bit too long for my taste (but the effect is lovely) and I'm currently trying out instants as it seems the Fire Island fits the bill nicely for a weeknight.... Anyhoo, any experience you guys could offer is appreciated
