What is your BP now with the meds and the last reading you had when the meds were prescribed ie without the meds. Also, what was the process and conditions when that BP reading was taken? Most readings in doctors offices are too high because they are rushed and the patient is not properly rested, calm and collected.
There are many BP pills prescribed without due cause for exactly the reasons explored above. Especially when you are willing to address high BP with dietary solutions. Do you regularly test your own BP at home (very easy to do)?
