Ten days ago I visited my doctor for a check-up. Everything was fine except my BP was 160/90. Doctor said, based on my recent history of good BP, this was not a "good reading" and that I seemed stressed. He asked me to relax and come back in a week for another reading.
I still cannot imagine what I was stressed over, but for the last week (on the advice of my wife) I completely eliminated caffeine from my diet - I had been drinking lots of diet soda and coffee.
Today's reading 110/60. I know caffeine can raise BP, but by THAT much?
