OK, it's self inflicted.
<whinge>
Somthing to do with the end of another sh!tty week, working my arse off for "da man" (or rather a large and aggressive bank, beginning with the letter "B", recently in the news for buying another large (but failing) bank beginning with the letter "L"), putting in stupid hours because of "market conditions", working weekends, not seeing my kids, not seeing my wife, sex being a thing of the past, no time to play my guitar, eating badly, not having enough time to go training, so putting on weight.
So I drank way too much last night, wine and whiskey. And I feel bad this morning.
But I got the call that me and my team aren't needed in this weekend, so that's something.
