I think the occasional alcoholic beverage on the same day as kava won't kill you, not likely anyway. Neither is it, IMO, a great idea, but if you want to and know you can handle it, that's fine, I guess. Just remember that the best is a small amount of each, but if it has to be a bunch of one and a little of the other, it's a lot better to have a lot of kava and just one drink than it is to have a lot of alcohol and then some kava, which is always a bad idea. Then again, the worst would be lots of kava and lots of alcohol. That could be very very bad, as in falling and hurting yourself bad just trying to go to the bathroom, room spinning, nausea out of control, .... Not to mention nightmares. I tend to see kava and alcohol combined as conducive to nightmares.
