who taught you how do do the self dialation. I'm strongly considering it as I have had 9 stretches now. Takes 4-5 hours from the time i leave my house, check in, do the procedure, wake up, check out and drive home. I've seen the You tube videos. they show that even if you are afraid, you can still learn. I'm on board. I just need a clinician to teach me how. where do you purchase the Maloney Dialators?
