Diagnosed with hypertension, but it seems my blood pressure higher in the morning. Currently on waking up it is about 150/95, however throughout the day this drops, particularly with activity. For example at about 2pm today afer moderate exercise, it dropped to 110/70 . I suspect adrenaline in my system may be causing this - I do snore and suspect a little apnea, but could it be excess adrenaline in my system which might explain this. My blood pressure now 136/89 at 11pm. Is it anxiety ? Currently on Quinapril (10mg) for just over a week. Just quit caffeine about 7 days ago,
