Ah. I was 22 when it happened. On a weekend, if I remember right. And yes, the young doctor on duty was very gratified by the instant relief, but not half as much as me. I'm not sure what he gave me, but it left me pretty drowsy for some hours. I didn't care, in the circumstances.
He cottoned on pretty quickly when I walked unsteadily into the ward office where he was chatting with a pretty nurse, & made "uurgh, uurgh" noises while pointing at my face & intermittently twitching violently. He looked stunned for a moment, but recovered himself quickly, & his first thought was to check what drugs I'd been given. He remembered the side-effect, but had to look up the treatment. As I recall, his mutterings gave me the impression he had a good idea, but wanted to make sure.
Apart from him expressing regret that he didn't have a camera with him to take a picture of me with my jaw at an interesting angle, I was quite impressed by his performance. All sorted in a few minutes. The antidote worked a treat, & damn quick. The nurse also seemed impressed, which may have done him some good.
They'd given me the drug to stop me throwing up everything I swallowed (I think my body really, really didn't like the general anaesthetic I'd had), as it was a Bad Thing after abdominal surgery, & I wasn't going to get better if I didn't keep anything down.
I presume my experience with Stemetil (etc) hasn't been repeated, or we'd have heard from Wowbagger by now.
