are you tired? I had one done two days ago and am still so tired that I just may fall asleep at my desk! Is it because of the lack of food for 2 days (I have been eating like a pig since then) or the sedation that has not worn off yet - which doesn't make a lot of sense after 2 days. Did anyone else feel exhausted after theirs?? btw - the colonoscopy was normal - at least something is!
