I echo what the others have said but let me prepare you for a VERY possible future scenario: You walk into the doctors office after a hassle day, his office is chilly and his stethescope like an ice cube. He takes your BP while you sit half naked, feet dangling over the edge of his examining table, wondering desperately what numbers he's going to get...seconds tick by: YOUR NUMBERS ARE 160/100.
Now the fun starts with the battling:
"I want you to add a beta-blocker"
"But doctor, at HOME my BP readings are excellent."
THEN he looks at you like you are a poor addled soul and says something like "But clearly under everyday stress your BP runs higher."
You are behind the eight ball, and unless you have a good BP history log and are willing to fight him on his own ground, you are doomed to more and more meds!
(He might mention "white coat hypertension" but don't worry, he REALLY doesn't believe it exisits- only uncooperative, quarrelsome, hypertensive patients!
This is a sad state of affairs but, I'm afraid itt's the norm.
IF you can do proper battle, and stay on ONLY the thiazide and continue with good readings at home, you are on the best treatment there is.
(Eat the bananas and orange juice...and take 250 mg Magnesium from some supplemental source.)
Good Luck with the JOUST!
