I was so worried about moving with the scope inside me, that's why I went with the sedation! As you said, concious sedation, but I only remembered bits and pieces of watching the procedure. I did take 3 peppermint oil capsules with my last water, as I've read it helps with spasmsI've had colonoscopy both with and without anesthesia....When it was with anesthesia, it was conscious sedation. Maybe it's partly because of all the fiber I consume in my diet and my insides are kind of used to... ummmmm... heavy traffic- but it wasn't that different for me. Both times, it basically felt like gas pains. But everybody's different. Even when I had it without sedation, they had to have the I.V. in me just in case, because every now and then, someone's colon starts spasming.
I had the first procedure with sedation, of course- it was interesting! I was kind of nervous, they started the I.V. (Versed and Fentanyl), and suddenly my nervousness disappeared- like they flipped a switch inside me. I think it was mostly the Fentanyl, which has been in the news a lot as a cause of deadly overdoses. I can believe it: when I read the report on the procedure later, it was only a tiny bit of Fentanyl they gave me.
My main reason for not having anesthesia is so nobody will have to come pick me up afterwards. Besides, if the stuff is that powerful, maybe it's not so safe? I honestly thought I could have gotten home on my own after I had it with conscious sedation- I get around mostly by public transportation and had no trouble walking. I can understand why they wouldn't want anyone driving themselves.
