Is it possible to quit BP medication?

1 month back I had chest pain so I went to a cardiologist he performed ecg and echo which was normal... at that time I was also taking the treatment for gastroenterology and had fatty liver and high SGOT 59 SGPT 117 and gas problem....he Also had my BP which was 150/90....so I informed him that usually my bp is in range of 135/ 85 so he recommended me sartel 20 which I am taking for last 1 month... height 5'5" and weight 68 kg age 30..... currently with medication my bp vary between 119-125/70-80......I also tried muktavati for 1 week it controls the bp very well but reduced the heart rate...most of the people are in the opinion that once we start the BP medication we can't quit it bcoz our body/heart become used of it...Is it true?
