I am the same, my office is in the back of a workshop so I have no natural light and the only time I know what the weather is like is if the guys come in covered snow or soaking or I need the loo and need to go a trek to get there - which I may add is an awful lot at the moment as I am drinking water again, seems when it is cold water it makes you pee more that drinking hot water!!!
Been an OK day today, very sore head this morning but have taken v strong painkillers so knocked on the head for the moment but it will be back - wee snooze when I get back home
Have a lovely afternoon x
