Still breathing. Those pesky minor details. I'm living proof that stress is NOT good for you. Sunday and Monday were the most stressful days at work so far for me. This caused tiredness, oxygen levels to drop to 91, and... Slept 10 hours that night. I also learned to sleep in a day cab at work. (no Covid tested to make sure) Just checked my oxygen levels and they were back to 97 on Wednesday evening. A good talk with my boss Wednesday too.. Hopefully things are straightened out now and that won't happen again..
