Same for me, djing for over 15 years Thurs, Fri, Sat, Sunday seriously fucks with your body clock.

Used to sleep Mon, Tues get up to buy new records Wed then spend whole day mixing then do it all over again.

Some nights wide awake some asleep early just no routine at all and been the same for so long it just seems normal now.

I got mates who work nightshifts and have done for years and like VD hardly sleep in the day.
