Hi Lisa,
I think taking a proactive position is always warranted with dealing with your physician.
Speaking from experience, being in compliance and taking your drugs during the years it takes to resolve your blood pressure problem is really difficult. Also, everytime you switch doctors they will either leave you on the meds your other doctor prescribed or start the process over again.
I would suggest you get/ask permission to use the following article, which is found on about.com.
