That is a difficult question. Now, in the evening, I just checked it, and it was 135/87
It is not always, though. Here are a couple of months of tracking, BP, pulse rate, date, time, notes:
118/72 71 04 Sep 2025 8:13 a.m. after only one cup of coffee
122/75 70 immediately after because I was shocked it was so low
148/86 83 07 Sep 2025 3:00 p.m. Realized I forgot to take my blood pressure meds due to chest pressure and head pressure, so took them after
111/73 71 08 Sep 2025 8:05 a.m.
147/87 96 18 Sep 2025 8:58 a.m. No blood pressure meds, 2 cups coffee
114/72 74 15 Oct 2025 8:36 a.m. 1.5 cups coffee, doing cardio for a few days
So notice a low of 111/73 and a high of 135/87 (right now). I did not include the two days I forgot to take my BP meds in the "high" category.
Also, I quit going to the gym 5 days ago due to work being busy (I know that should not matter, but my blood pressure is lower when doing regular cardio and hitting the gym and it can literally go up a few days after stopping and go down after a couple of days of doing it) and I also think it is higher in the afternoon and evening than in the morning after cardio and taking my BP meds and sitting down with my cup of coffee to get on my computer and start working, and, oh, I will take my blood pressure right here in the a.m.
I think the afternoon/evening rise might be due to the short acting nature of metoprolol, which my doctor has prescribed once a day (and objected to it being used twice a day, but I occasionally -rarely- take it in the evening if I feel things getting higher, that pounding in the chest feeling)
