Awww soz to hear you're having a bad 'work' patch John
At least these things make us take stock and do something about it so there are positives there.
I have a fairly stressful job, love it but get very tense nonetheless, therefore I bought a cross trainer and treadmill. I get home and if I've had a bad day I pound around on these and feel great afterwards, the bonus is a good serge of energy too and hopefully a smaller bum eventually
Mind you, the 3 glasses of red wine everynight help with stress too !
