Doing better today, much more stable, but on the downside, have also felt utterly mindless half the day... like the engines running but no ones behind the wheel. Ok, so I've got a few cracks in the crockpot, ain't the first time :-P.
In a rather interesting twist, normally I would play games to take a 'break' for programming tasks that require long periods of concentration: good choices being most things Id Tech or Unreal Engine based. Tonight, I instead found myself playing Chess to build up towards concentration, lol.
Well, as stupid as that sounds, it works :-S.
