Lovable, they put you out before they start doing anything and you wake up after it's all over and done with, so you shouldn't feel embarrassed; you stay clothed the whole time you're awake. Unlike the GYN, lol. Mine laughs at me when she checks my heartbeat because it's always racing. Never mind nothing she does hurts; I'm just very embarrassed by it. Definitely less embarrassement with the scope because you never know it's happening.
I got over-drugged for my colonoscopy too. The nurses couldn't get me to wake up and so they brought my mother back to wake me. Then I kept falling back asleep, so she had to dress me, lol. I woke up occasionally while they were trying to get me out of the hospital, and I walked into a restaurant for breakfast, but I am quite sure I slept through eating! When I got home I slept all day (I was back home by 10 o'clock--mine was very early in the morning) and didn't wake up until about 8 or 9 that evening. So I can honestly say I don't remember a thing about the procedure... or much else during the rest of that day, lol. But, from what I have heard on the board, it's not common for people to be that sleepy afterwards. One lady said she could have driven herself home she was so alert afterwards. I guess it depends on what they give you, how much they give you and how you react to it. Me, I'm a good sleeper anyways, so I must have really reacted to it!
I'm 26 too. My gall bladder started acting up when I was 18 and I had it out when I was 23, so no, you're never too young for this stuff. I also have a family history of bad gall bladders.
