I'm trying Kava Tea instead of coffee this week, well, coffee *at work*; me driving in the morning without my Peets Major Dickasons blend would be just too dangerous to both myself and other road users! The one time I tried giving up coffee completely led to a scar on my car's front bumper and the loss of my car pool driving privileges (now I don't car pool at all...).
Supposedly Kava has an anti-anxiety effect...so I'm hoping it calms me down and helps me structure my thinking a bit more easily.
