This is very embarrassing question, but I have to ask. I have a severe phobia when it comes to doctors and needles. I am 52, so based on my age I should have had a colonoscopy 2 years ago. Instead of an IV, is there a different procedure they can use to put me to sleep, in order to do this. I have talked to a psychologist before and it did not help, so please don't tell me to do that. My husbands response, is just get over it!
