I posted earlier that I get my Colonoscopies without sedation because I can't tolerate any of the meds. I forgot to add one thing.... My GI uses a "Pediatric" scope that is somewhat smaller in size and is used for children. It is just as long, but more narrow. It is much easier to tolerate and you still see the same thing! My GI is also very gentle. I do tolerate it very well. Hope this helps. Julie
