'going to the dentist hurts more.'
it's a cliche', that statement above, but true in my experience.
i was scared on the 1st one. no need. they take very very good care of you. after the first one i as like 'what's the big deal? that's it?'
it also worked. i stopped after 12 unilateral. the doc wanted to do more, but i felt i had done enough. i might try it again.
