Hello scooter,
High systolic blood pressure with "normal" diastolic pressure still means that you have hypertension, that will likely need additional medications.
From a treatment standpoint, I wonder what medications you are on currently and the reason you've been switched between several different medications.
Generally, a good strategy for treating high blood pressure involves increasing a particular medication to its highest dose and then adding other kinds of medications if needed. A diuretic like hydrochlorothiazide is an excellent, cheap, and side-effect free starting medication.
Please keep exercising and eating right! Even if you need two or more medications to control your BP these activities help your health tremendously.
To your health,
Neil MD
