Cozaar and natural remedies

I had been on Cozaar off and on for about three years. Although the medication did bring my blood pressure down, my weight steadily increased, and no matter what I did, I could not lose a pound. I was tired, depressed, and my vision changed for the worse. I had increased urination, and I also developed a strangling type cough, and would have coughing fits every now and then. I experienced light headedness and a loss of concentration. Initially I did not attribute these symptoms to Cozaar, because they came on gradually. I never needed glasses before Cozaar, my appetite was the same, and I was not on any other prescription drug. About 6 months ago, I decided to ween myself off of Cozaar. During that time I have lost about 20 lbs, without dieting--eating the same way I did on Cozaar. My concentration and energy level has increased, and my vision has improved--I don't need reading glasses anymore. My blood pressure fluctuates from normal to medium-high, so I am looking into more natural remedies to control it. Please remember that drugs treat the symptoms, not the disease.
