Thanks for that reassurance, Boaty.
David was making me feel guilty about the glass of plonk I've just poured myself. (I'm hardly going mad with the stuff; it's the first one of the night!).
I went shopping on Monday and decided that I wasn't going to leave the house again until Saturday, so I've no need to worry about drinking and driving and I've got no reason to look at the clock. So I'll just go to bed whenever I feel like it (and for as long as I like) and have the odd drink or two whenever I feel like it. I've not bothered with shaving since Monday (and I've only gone through the motions of bathing) but who cares? I'm really enjoying being a slob - it's pure luxury! ;-)
