<s>[INST] 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, [/INST] Hi, Blood pressure levels are quite individual, some people can have high blood pressure in the morning, some in the evening and some during the whole day. Actually sleep apnea can contribute to the rise of blood pressure in the morning and at night. In this case treatment of sleep apnea is indicated. Usually I prescribe blood pressure medications at night such patients, to have maximum protection during night and in the morning. Hope I could help nourishing you good health In case of further questions don't hesitate to ask </s>
