Suggestion w/ the eyebrows thing (goodness, i need mine done too)... if you're worried about pain, take a couple Advil or your analgesic of choice about 45 min-hour before you go in... I read that in a magazine somewhere. I also read that most people have a higher pain tolerance in the mornings, so you might want to keep that in mind.
