Thank you 2sp, tonyav, maydup, and triggerhippy. 2sp gets the best answer because of the DNA quip.
The injection still hurt like a female dog, although I recovered a lot quicker than before. I would like to think that the anaesthetic has not worn off yet, as I cannot feel my right big toe although I can move it for the first time since August last year. Fingers crossed this injection will work, although it can take up to 2 weeks for it to start kicking in, as it were.
I am off to reformat my book to the publisher's specifications now, that's going to take me a fortnight to redo all the page numbers and make sure all the text fits the pages. While I am gone, have fun on AB for me.
