I need help with my medicine.  I'm worried it's making me worse.
Could I get your name, please?
I'm Ben.  I saw Dr. Johnson the other day and need instructions on how often to take my medicine.
Your instructions are: Take your medicine before you go to sleep. If you experience nausea, please contact your doctor immediately..
Wait, I'm sorry.  Dr. Johnson was my previous doctor.  I saw Dr. Alexis the other day.  I really need to find out how often to take this medicine so I don't overdose.
Your instructions are: You must take your medicine 2 times a day before meals..
I actually like Dr. Johnson better than Dr. Alexis, but Dr. Johnson refuses to prescribe me these pills anymore.
Is there anything else that I can do for you?
Wait, 2 times per day, before meals.  Okay.  I've been taking a couple dozen per day.  That might explain how I'm feeling.  Thank you for your help.  That's all I need.
Thank you and goodbye.
