I've opted for no sedation, Fentenyl on-hand only if I request. I discussed it with my GI at my initial appointment, so I won't be signing sedation consent if presented with one.
I don't want more meds than I need, and sedation drugs (midazolam/ Versed) do nothing for pain anyhow. It's a simple procedure, and I'd rather witness everything they're doing to me, remember it, and lucidly request/demand additional pain meds if need be (or stop the exam entirely if they can't reduce pain - my right). Better to be safe than risk being in pain,unable to move/communicate, and have my demands to stop ignored because I'm not credible under sedation and they know I won't remember it anyway.
I don't want just the memory of pain removed; I don't want to experience pain at all. Pain drugs only - no Versed or anesthesia, unless they need to cut me open.
