Any luck lowering BP naturally?

Im interested in lowering my blood pressure naturally. Im 40, in decent shape, 20 lbs overweight and my BP has stayed the same for many years (usually around 140/90). Im not ready for medication and want to lower it naturally. I have to get a DOT physical every two years and every time its right on the border of pass/fail. The doctor pushes medication, medication, medication to regulate it and every time I tell him to take a hike, but Im getting tired of sweating it. What has worked for others for naturally lowering BP? Its really only got to be a couple points lower for me to be comfortable.

You stated that you are 20lbs overweight - that would suggest you don't have the best diet going on. You're Dr. sounds like a quack if he's only pushing medication and not telling you to change your diet or start exercising. Maybe lower your sodium intake?
