I am a coffee addict and consume some 40-60 ounces in the morning at the 'puter.
I have been getting superb BP numbers (under 115/75 from my short trial of only Lasix furosemide, 80 mg. BUT the last two nights my numbers were over systolic was over 140 in the evening (I do all my measurements after 6 PM.)
The last two days I did something very different...I had another 14 ounce mug of coffee after dinner and before testing my BP. Both days, it remained high til midnight.
I guess there's no denying that strong coffee raises my BP. If I get brave, I;ll take my BP at NOON one of these days.
So, no more at night...EVER and I really should cut down on the morning coffee. Who knows maybe if I can give it up, I'll be a normotensive...or a HYPOTENSIVE.
Since I had coffee and a roll before starting KINDERGARTEN <no exaggeration> quitting would be nigh impossible, but I COULD limit myself, MAYBE, to 24 ounces per morning.
OHHHH, the thought of the headaches and possible COMA!
Have you noticed any correlation between coffeee drinking and HBP in yourself?
