Hypertension. Come out of bp medication?

Hi, im 38 years old male. presently my BP varies between 120/90, 130/90 and max on stressful days at 140/90. It also is some times 120/80 . When I was randomly diagnosed for the first time it was 150/100. Now after lifestyle changes and walking for 1 hr a day, my readings remain in the above mentioned range.i was initially told to start telma 40mg. I took these tabs for 3 months. Now from 2 months I'm taking telma 20mg. Still the BP range is same with lifestyle changes made. I have a very active lifestyle and I'm on a vegetarian diet with occasional non-vegetarian food. Is there anything more I can adopt, to make the readings better? Tests for kidney, heart and liver are all normal. Can I come out of BP medication?
