I am having issues.
Could I get your name, please?
It's Mark. I saw Dr. Johnson, I am not sure about these medications he gave me. Maybe I didn't understand the instructions.
Your instructions are: Take your medicine before you go to sleep. If you experience nausea, please contact your doctor immediately..
Oh, actually it was Dr. Morgan I saw last time. These meds have me all messed up.
Your instructions are: You must take your medicine 2 times a day before meals..
Ok, maybe that's the issue. I am not taking it before I eat. I will try that tomorrow.
Is there anything else that I can do for you?
No, thanks for reminding me about the food though. 
Thank you and goodbye.
