Too much of a....thing

I can't say 'good thing', because it involves work. I agreed to go in early last night to cover some emergency leave, and ended up working almost twelve and an half hours, leaving me pretty shattered by the time I got in this morning, more than fourteen hours after I'd set out. I slept reasonably well today, although I never seem to get quite enough sleep when I'm on nights, but that wasn't enough to encourage me to accept the offer of yet more overtime when the late turn shift manager rang me a short while ago, staying on tomorrow morning after the scheduled end of tonight's shift. I already feel like I'm coming down with some bug or other, possibly a chest infection - I'm coughing well, at the moment, whatever it is - and I really don't want to risk exacerbating that situation by ratcheting up my fatigue levels even further. I'm pretty resilient, normally, but even I have some limits.
Too much of another thing, too, in a way. I was tempted to write about a couple of encounters I've had in the past three mornings, strictly visual only, at 'work-town' station, facilitated by my catching a slightly later train back than I usually would, because of the position I've been covering this week, but I haven't got the energy or inclination to become embroiled in another round of recriminations like last week's. There are times when I'll accept the consequences of putting myself 'out there' to be shot at, and fight my corner accordingly, but now isn't one of those times.

Love & best wishes to all
