Thanks, Zuzu, and Blue Island for the info. Although hypertension runs in my family, I was not diagnosed with it until I turned 50. Coincidence because of age? I have always been on the slim side, 5'6", 124#, exercise religiously, and do my own baking (whole wheat bread etc.)and cooking, monitoring the sodium in the recipes. I am a lite smoker and have an occasional glass of wine. I do believe that age as well as stress and genetics are a major factor, but I am beginning to feel like a guinea pig, as none of the prescriptions seem effective. The Toprol XL is in addition to Uniretic, an ace inhibitor/diuretic. Thanks for the response.
