So I'm getting used working midnights again, and overall it hasn't been too bad, what with the 5 on 3 off schedule. I've been able to get a full sleep cycle most times, even if it is during the day. I've decided to stay on my schedule even on my off days, but this time around, I seem to get a headache at various points of my time awake. Anyone ever run into this before? I've been on midnights with my prior department, and while I picked up a coffee habit, I never ran into this. Any suggestions would be greatly appreciated. Thanks, guys!
