personally i wouldnt take it. but i dont know if you have any other pre-existing conditions that would make you prone to a stroke or heart attack. its considered high at 160.
if you adjust your diet and exercise a bit you probably will low enough that your doctor will take you off it.
i had my dad do that and it lowered his bp and he is off his meds and has no more ringing in his ears. plus he passed over 40 kidney stones and sand from that cure.
