...I'm not going to volunteer for them any more.
Sunday I worked a double on the med cart. I had time to eat both lunch and supper, so low blood sugar was not a trigger, but the weather was lousy on Monday. Anyway, when I woke up Monday morning, Madame Migraine was there with her whips and chains. Nasty old hag.
Anyway, I'm scheduled for another double on Saturday. I'll know Sunday morning if this is going to be an issue or not. I think I'm more of a marathoner (working many days in a row without a day off) versus a sprinter (working doubles) anyway.
