I would seriously only recommend one even TRY w/ Dr assistance. Many (most) BP meds can cause seizures if you try to stop them too quickly! Don't ever try to be your own Dr. The reason these meds are by prescript only is bc you need to have training to know how to properly administer and STOP administering them. Im takingmy first pharmacology class now and its scary stuff to try to dance w/ w/out professional advice.
