I've had 3 colonoscopies without meds. I think its the doctors expertise that matters. The first 2 by Dr. Hale were not bad at all, the third quite unpleasent. I'm due for #4 in a year. During the first I was breast feeding and didn't want meds, the second was the same doc, the third I was in for 2 procedures and couldn't be sedated unless the 2nd procedure was canceled. Don't think I'll do that again. I never "talk" about it but I might as well. I've had hepatitus C since the 70s. So I am anti meds in general because of liver issues. The 2nd procedue was a liver BX. Had my 3 kids no meds.
