Mine went fine last Thursday. I had a similar timetable to your DH, Daphne, and although I was worried about final trickles after 10 am, they stopped just on time. The Moviprep was disgusting - tasted OK at first, but I had to leave the last two gulps of both doses, or I'm sure I'd have been sick.
I was lucky that I only had a 10-minute drive to the hospital and my appointment was at 11 am (DH took me in and fetched me). I had a general anaesthetic (The drug used was called Propofol - this may be a German brand name) and went under at 11:12, came out at 11:44, feeling quite rested. Absolutely no after effects - except I was hungry, of course, and cooked us bangers and mash as soon as I got home and even went out for a meal that same night.
Results quite the picture book (yes, I was provided with photos as well!), and as a formality some samples were sent in for testing but I don't expect any worrying results from that.
Oh - and I had warned him that there might be some unexpected bends, as I had had three children and things had been re-arranged quite a bit, as other doctors have already told me. He said it was a bit more windey than usual.
