I understand your anxiety, John. Perhaps like me, your phobia's stem from bad childhood memories when they gave no pain killer for anything but extractions. (That's right, nothing for drilling - not even for children!) I have a 2 PM cleaning scheduled for Tuesday myself but my hygienist is a real sweetheart. Always asking how I'm doing, ect., she really calms my nerves. I'll be thinking of you tomorrow and hope all goes well for you.
