My recent memory problems, worsening balance, very short "battery-life" (just don't have energy, really) - all of that seems to have either appeared or got worse since the surgery (or if not the surgery itself, then the general anaesthetic).  The worse, and to some extend even embarrassing, is that I can't keep my eyes open: all of the sudden my vision blurs, my eyelids become extremely heavy and my body is hit by a wave of 'muscle-relaxant' (where from???) - and, as I call it, "the lights are off".  I described it as if it was at least few minutes, but in reality it happens faster than my ability to react!  Few seconds, really.  D.P., who kindly helps me with typing since my wrists are too damaged for the honour, recognises it after my sudden slurred and completely illogical comments (last time it was something about a trey of biscuits, apparently - in the middle of dictating her a long list of "article 1, section 2, point 3, Journal of Bills 2004, issue 5, entry 6" - and there was something like ten or more such "addresses"...).  Thankfully she saw through me immediately and suggested, that she has to go home to get keys (which she forgot to bring with her), so maybe I'd like to lie down for that time and cuddle Jacky - no objection there.  When I got up an hour later, I didn't remember any of this - but I was much refreshed and invigorated...
