There are even different kinds of krunk. Sometimes you have to do the one eye thing. Sometimes your eyes are fine but your legs turn to rubber.
For me, heady kavas are more likely to knock me crosseyed if I go hard, yet the effects are slow rollers, suggesting that they come from "heavy" KL's (or maybe metabolites of the heady ones?) The nicest clean heavies will get you all loose without as much eye distortion or nausea. Sometimes you won't realize how cut you are until you try to walk.
