I think you should try known natural remedies before going with BP Meds. Those meds, while providing a quick fix, do have long term negative results. One of those is a significant increase in cancer risk.
Cut the salt out of your diet as best as you can at least a week before the medical. Also eating known BP reducers like beets, celery, turmeric will help. There is a great drink mix that I like from Humann called Superbeets. It will drop your BP at least 10 points and help you keep it lowered. It seems like most AMEs use that automatic BP machine now, and that does show a higher BP than the old manual one.
