Successful Operation

I'm sitting in a hospital bed at the moment as on Wednesday I had an operation (planned histerectemy) and I can't seem to drop back off to sleep. I was fast asleep until just after 11pm and then the nurses came in to do the observations. Anyway here I am wondering what to be grateful for, I suppose I should be grateful that the op went well and I'm not in much pain, and that the drugs they pumped into me yesterday made me so drowsy that I had some sleep. I quite like that really drowsy feeling. Ashame it didn't last just little longer.
