I'll start off by saying I never get sick. It's pretty obvious when you need antibiotics though. No history of allergies. I used doctor on demand for the first time today, Dr. Scott Martin was really rude. He was more interested in gathering information for the CDC then he was giving me antibiotics for infection that I'm coughing up and blowing out of my nose. When I told him that I didn't want my information going to the CDC he become really rude. Following that, he hung up on me. Don't use DOD
