High Blood Pressure
"Had first bypass op in 1982, second a triple in 1992.  I have been taking 50 mg tablet per day (for 25 years now age 84. I take half the tablet in morning and half at night ( my own method ) have found this best for me. Have a little Fibrillation from time to time, in the form of hard heavy beat lasting about half hour. My blood pressure is good tending a little to the low side, pulse normally around 55-60. Have not had side affects that I am aware of ?"
