Where is your friend? I don't think you can treat hep c with just Harvoni you must take a combination of drugs depending on your type. Read gregg jefferys blog if you can it gives you lots and lots of information.
It cost 100.000 here in Michigan and I will start my treatment soon which I found out I have cirrhosis they said I only take horvoni once a day and they will check my blood at times. This is it. No second pill or pills.
