Hello sir, The information regarding present blood pressure reading is missing. In the absence of that, I would assume that your doctor has made a decision looking at your blood pressure going down may be below normal. You can stop the drug as indicated by your physician. I would recommend you to have regular blood pressure measurements, follow ups and report immediately if you have any symptoms of giddiness or headache. I also appreciate your effort in including lifestyle changes. It goes a long way in addressing the problems of high blood pressure. Hope the above information helps you. Thanks for writing into healthcaremagic. Have a wonderful day ahead.
