I went to the doctor because I have been having a horrible time sleeping. The nurse took my blood pressure and it measures 145/95. However, I am always super nervous while at the doctor. So upon pikcing up my meds, I purchased a blood pressure monitor at the pharmacy. At home while relaxed it measures 128/84 and ranged up and down a little until I went to bed. Upon waking, when I was just getting up, it measures 119/74, but after I ate, had half a cup of coffee it measures 136/88. So since mine seems to vary so much, active up and about versus in bed and relaxed, how does one gauge whether or not it is high ? Thanks
