hmmm... how does all this tie in with people like me on high bp drugs like lisinopril and the water pill HCTZ?? I am over weight of course, but have been on high BP rx even when I wasnt, they say it is heridtary.. any ideas? I know I can tell when I am low on potasium. (lisinopril is potasium sparing and hctz isnt) so I add no salt at times. Im not sure what is right for me.
