If you’re on new medication keep a log/diary of how you’re doing on the meds. If you have high blood pressure, buy yourself a Blood Pressure System . Then using Excel or the really cool, FREE openoffice.org version you can keep track of your data. Using a spreadsheet is especially good because you can print out the data and manipulate it to learn other things.
You’d be surprised how often you think you have everything remembered only to be reminded by things once you look in your diary.
