My dad had BP issues - (not on Hinz on protocol ) extreme highs and fainting /falling/ER many times ...
Turns out that was related to his additional meds, we reduced & then eliminated one at a time to track it down, with drs approval ..
There was also increased delusions/hallucinations - which resolved luckily with the stopping of these extra meds.
Mirapex (generic)
Vesicare & Flo Max - also tried any older one but it didn't help w/ night-time bladder issues either so we stopped it.

Currently dad does get some low BP fluctuations, but after a deep nap he is refreshed and fine. But no more extreme high BP w/passing /falling / trips to ER...from hitting head on floor..

He was able to take those other meds for quite awhile ,before having the high BP, but maybe age (80+) or it just became too much extra stuff accumulating for his system to deal with..

My thought is look at any other meds you are taking , even if they were fine for you for quite awhile, you might be able to eliminate something and feel better..
