Memo to self: When you are lying in bed, drifting in and out of a dream state, and feeling extremely thirsty, then despite all appearances the uninspiring glass of slightly warm water sitting by the side of the bed is infinitely preferable to the enormous tankard of chilled and nice-tasting Ribena in your dream. DRINK THE FORMER.
In other news, I'm now back at work, and by my initial estimate it will be mid-to-late afternoon before I finish clearing up my email backlog from the last two weeks.
Also my knee appears to have stopped being extremely painful, and now merely feels slightly fragile. Another week of being gentle to it and it should be back to normal. Still no idea what happened to it (and the doctor was unenlightening), but phew anyway.
