I've been dealing with high blood pressure and tachycardia since 2012 and it's been pretty frustrating. I've done all sorts of tests and nothing seems to be working out. It's especially annoying with the tachycardia because whenever I start on medication, it works for a bit, then just stops being effective after a while. Right now, I'm taking a mix of meds including metoprolol 150mg (50mg three times a day), ntp 25mg, prazosin 5mg, diltiazem 90 Sr, cilnidipine 10mg, and losartan 50mg among others. This whole situation is starting to feel a bit hopeless. I'm curious if there's anything else I should be trying, or if there's some reason these meds lose effectiveness so quickly. Any insight you could give would be really appreciated.
