Nope Irish, I actually said that to the wife today about it being dark early that it's a pain in the arse. I believe that a lot of people are not in great form this time of year. We are over the worst if it now, there is little stretch already in evening light. I'm actually looking forward to getting back to work now (probably not too many say that) I'm back on Monday.
The contrast between the full-on Chrimbo and New Year and then the screeching, pitch black halt it all screeches to I think messes with a lot of heads as well.
I actually think the relative normalcy of going back to work is a welcome relief for a lot of people!
Hope you feel better next week as the days get a bit longer and you go back to work.
