Well, today I have proof. There are three mosquito bites on my ankles and they are only mildly annoying, rather than near madness-inducing. If this is the way most people react to mosquito bites, it's no wonder they haven't been ruthlessly wiped out yet. Pre-Claritin this many bites would have me feeling vaguely ill, in addition to itchy-to-the-point-of-utter-distraction.
Gosh golly gee willikers, more proof this stuff really does work!
