+1 for openoffice... it has an excel type of application that is pretty easy to use.
As for BP, high BP runs in my family... I was diagnosed with it over 5 years ago when it was 170/110 and I was getting headaches all the time. I'm not overweight and I exercise about 1-3 times a week so it definitely was hereditary. Now that I'm on meds, my BP is around 130/85 which is still a bit high but way better than before. I also use an Omron BP monitor at home and they are pretty good and easy to use.
Btw, if you don't already know, your BP will fluctuate throughout the day depending on what you're doing... if you're in the middle of exercising or, are stressed or anxious, it will naturally increase but, if you're resting, the ideal BP is around 120/80. But one-size does not fit all; if your average BP is a little higher than 120/80, that's fine... excessively high BP can lead to other more serious ailments like heart attack, stroke, diabetes and it puts pressure on your other organs, especially kidneys.
My MD's have not been very helpful with suggestions on managing it as they are overworked but, after much research, I decided to take action... reduce stress, exercise more, threw out the salt shaker, stopped having McD's and reduced sugar and I'm trying to enjoy life instead of focusing on the rat-race...
sunspot, good luck to you - I hope you find the tools necessary to help you track your progress and I hope everyone in this thread is also able to manage their BP.
