The Unbearable Itchiness of Being

The title probably speaks for itself, but man... am I itchy.  And can't sleep.  I was actually asleep for about 30 minutes tonight, but I was awakened by a roving itch that struck me in my feet (not unusual for me) but now in my thighs, armpits, head, groin.  Man this is annoying.  I don't know if this is a chemo thing or not, since I've been having trouble sleeping anyway.  Aargh!
