The first time we had a colonoscopy WoBG and I had them scheduled one day apart. Mine was on a Monday, WoBG was on Tuesday. I remembered when the doc told me I'd be able to talk and answer questions, but I'd have no memory of anything until I spent about 1 hour in the recovery room.
So.... when WoBG got out and met her in the recovery room, she had to remain there for a bout 1 hour or a bit more. We had a conversation for the entire time. I asked her about things we talked about later. For the first 30 to 40 minutes in the recovery room. she had NO memory of anything we talked about.
That's when I got concerned OMG what did I say to her yesterday? I assumed it must have been OK... she wasn't mad at me. I told her what I remembered of our conversation. Yeah... the first 30 to 40 minutes... no memory of anything. She told me the doc came into the room. Nope... I didn't remember any of that happening.
