Honestly, bluesky, it's a doddle!
When they put the stuff in the canula to make you fall asleep it's like having downed a few drinks - a bit woozy, but not uncomfortable at all. That lasts for about ten seconds while the doc tells you that might feel woozy. I usually have just about enough time to slur happily that it's working and then I'm fast asleep until I wake up in the post-surgery room. Usually there is someone right by your side holding your hand (I've had that both on the NHS and private) and after the light anaesthetic of the d&cs I didn't feel groggy at all. You might have a slightly scratchy throat after because of the tube they put down while you're sleeping but the feeling is more of a thirsty type and you'll be encouraged to drink water soon after waking up so it goes away quite quickly.
I'll keep my fingers crossed for you that everything goes well and the remaining tissue will be all taken out during the op! xxxxx
