Anyway, this thread has scared me into going and finding another doctor and getting some BP meds which work.
That scam doctor's office I went to in February prescribed me some meds which work for my brother, but were ineffective for me (they literally did nothing).
Thanks to shitty Obamacare making very few doctors available to me (at least ones which take new patients), I didn't bother going to find a new doctor to try other meds. So I'm still sitting on a 152/92 type BP, which while not immediately dangerous, is not good to be sitting with in the long or medium-term.
So I'm going to bear down this week and find a place, and get some different medication for it.
