I have serious issues when things through my normal schedule off track. I do run circles for work but being able to not have any issues at night sleeping are okay, until something goes batty for whatever reason.
One night we managed to have two different car alarms going off, someones house alarm and an angry dog running around barking. This was all within a six hour time span and that next day into work was like dragging me through quick sand trying to get anything accomplished.
