Jim had some excellent advice. I used to work EMS, so I would add the following- for most people. your blood pressure will be highest in the evening, and lowest in the morning and also after a meal, when the blood has flowed to the area around your stomach and intestines to absorb the food. Sometimes you don't really have high blood pressure at all, it's just a temporary result of other factors, but of course, you want to be sure.
If you have a couple cups of java, walk into the Dr's office and sit right down and let them take your BP right away, without a little relaxation, it can be high . . . so, sit down, relax, ask them to give you a couple of minutes, breathe in and out slowly, and just try to relax a little, and you may find you're normal after all.
You can also buy a handy little wrist-mounted BP cuff at Fry's or some other electronic stores that will monitor your BP for you. I would try one of those out for a few days, long before I would commit to a lifetime on some medication. You may find you only have high BP in your DR's office.
I would look into it a bit, before I let them put me on meds . . . If you dive, be careful , some BP meds could kill you, and no one will warn you about it, because it is not well known. . . . but it happened to someone very close to me.
Free advice, and worth every penny.
