Mrs. Wokeme: "Yes, I see you for migraines, and I have one. What should I do?"
Dr. Grumpy: "Didn't I give you a prescription for Painbegone? Have you tried one?"
Mrs. Wokeme: "No, but I have the package right here. It says to take as needed for migraine."
Dr. Grumpy: "So take one, if you have a migraine."
Mrs. Wokeme: "Okay. I just wanted to be sure. I thought I once read that 'take as needed' was some sort of medical code meaning I should call the doctor first."
