So you've had a stressful week. You had to do some extra long hours to stay on top of things and make sure you've got enough money at the end of the month. The stress has you sleeping rough all week and you've woken up groggy every morning with barely enough energy to get up let alone make breakfast. So you reached for the coffee and got on with the day on an empty stomach. By the end of the week you're exhausted, accidentally falling asleep in front of the TV, maybe you feel like you're catching a cold too. Next week you'll get back into your swing of things.
