In the morning, my bp is around 120-130 over 78 ish. In the evening, it can be around 140 over 93, even in the 150's some evenings. I take Lisinopril 50 mg in the morning. What causes my blood pressure to rise in the evenings when I am relaxed, rather than in the morning when I'm getting ready for work? Should I try my medicine at a different time, perhaps at lunch? Will exercise or stretching in the evening help lower it?
