msgulch,
thanks for the post.
I think you should discuss your concerns with your physician. He/she may have put more thought into your diagnosis and treatment than you think.
If your concerns and worries are not alleviated then perhaps a switch of phsyicians to someone you are more comfortable with might help.
I generally check blood pressure over 2 visits and use ambulatory readings as well as some simple blood test before initiating treatment. The may have been done recently or are being planned by your physician in the near future.
Good luck
