Like a PP, I don't react strongly to medication. I tend to need higher doses in general. Stuff that knocks other people out might make me a little sleepy at most, etc. I can easily wake up again after falling asleep after taking a sleeping pill, and be completely lucid and functional, etc. They need to give me a lot of Novocaine at the dentist, and they had to put me on the max dose of Pitocin to get my labor going, etc. After I woke up from the one surgery I had, I was just tired, nothing more.
My husband is one who reacts violently and fearfully after being sedated, though. After one surgery, he was really upset, yelling and wanting to get out of bed and having to be pushed back into it, etc. He started singing to calm himself, which weirded out the medical personnel (although it worked). I was there waiting for him, and I don't know they didn't let me go back, as seeing me might have calmed him. I'm assuming they were worried that he might *not* recognize me and still be violent, and there'd be a lawsuit or something, I don't know.
