High blood pressure is not curable, but it is manageable and the moment you let go you risk increases in your blood pressure. To counter balance the reduction in medication and the eventual total stop, natural lifestyle changes will be helpful in controlling your blood pressure for the long term. Take into consideration, that you may not be able to reduce your blood pressure with just natural treatments like eating healthy, exercise, Resperate, etc., and you may have to return to taking medication. If this is the case, then you should continue maintaining a healthy lifestyle and see if the combination of natural treatments and drugs are more beneficial.
It is also important to regularly monitor your blood pressure closely as you change your treatment strategy to see how your body reacts to the changes.
