I had an appointment with Dr. Alexis. I'm really worried about what the medicine is doing to me.
Could I get your name, please?
It's Mark. And I went to Dr. Morgan on this appointment. Old Dr. Alexis was my doctor some time ago.
Your instructions are: Take your medicine before you go to sleep. If you experience nausea, please contact your doctor immediately..
Well, I had a rash and was concerned it was from the medicine. 
I'm sorry. I can only help you with the instructions from your doctor.
Okay, well thanks for your help. Goodbye.
Thank you and goodbye.
