I'm sorry to hear that Sue, High Blood Pressure runs in my family. My dad has to monitor his every day. But as a general rule its best to try and exercise more have a look into your diet like more wholegrain, not too much fat and also eat some fish every week (fatty omega like trout, salmon and Mackerel) and try to reduce both your salt and eeeeeeek alcohol (sorry)
There's a good website I have found
