Ways to lower your blood pressure?

[chance]

Alright, I'm in a tight spot. Last Monday I go to the doctor for a cough that has been going on for about a week, and of course as soon as I walk in they take my vitals. Everything is good except my BP its 156/98, and when they recheck it later it's still high as crap. So the same day I take drastic actions, I cut my sodium down to 1500 mg a day and my calorie intake to 1800 a day plus no energy drinks, soda, alcohol or any other form of sugary drinks only water. I've started doing PT again seeing how I can go longer then 5 minutes without going into coughing fits.

My question is what other things can I do to drop it naturally that won't effect a physical I have to take in 2 months?

Thanks in advance
