Ah well - see I'd never had a GA, so I suppose I could just as easily have had a dodgy reaction.
Think it lasted about 45mins max. Can't really remember though. Was in the unit at about 10am, and dh picked me up at 4pm. Fasted because everyone had to, which was fair enough.
I didn't have time off because was SAHM. My DH was told he couldn't have time off to look after me (another story!) and my mother ended up having dd during the day for the 2 days after. And then was the weekend, so by about day 5 afterwards I was pretty fine really - in terms of healing and generally painwise, was oodles better than after I had dd (but then that time the stitches were pulling all the time, obviously had been a bit of a cock-up). Whereas I got an infection after dd, the restitch healed beautifully. Was done in completely sterile surroundings. Though I think I did have my period when it was done, I just used pads afterwards.
The actual injections were nasty (for me). I think I wasn't expecting that, and so was unprepared for how sore it would be. Had lots of them, with varying degrees of success. To be honest, I think part of the reason I got wound up was being in the op theatre, and the stirrups, and just found it hard. I am sure that you will be fine fine fine though. And I am so glad I had it done, because was simply impossible to have sex without, and I now have ds! INcidentally, I tore only slightly with him, stitches afterwards were fine and history didn't repeat itself.
