Coffee doesn't have to make BP go up if you learn how to self-manage anxiety and stress. It's tough but doable. I had high BP for years when I finally realized it was because my mental habits were a lot worse than my physical habits. Realized that I spent way too much time worrying about ****, when ultimately you don't control anything. All you can do is aim for a goal, and don't sweat it when you experience an inevitable bump in the road. Just put it behind you and keep aiming for the goal. Took about a year of having to remind myself to chill out whenever I felt my anxiety and worry rising.
Before, a coffee would peg my anxiety and since I did nothing to curb it, it went buckwild. Now I can drink a coffee before bed and snore like a baby. It was mostly about controlling anxiety for me. My BP was stuck at 150/100 for years despite the fact I was fairly active and trim... now my BP is a calm, cool 120/85. My doctors were trying to stick me on blood-pressure and anxiety meds, I told them I wanted a chance to lower it myself, and he flat out told me he didn't think it was possible.
I'm a competitive ****er about certain things and when it dawned on me that anxiety was "winning", it pissed me off and that was that. Not a fan of losing, especially to something that was created by me.
