Reduce blood pressure in 3 days

Hi ALL, I regularly consume 5 mg lisinopril before sleep for years and I regularly check the blood pressure with the range 135 -100 up to 145 -110 during normal working days. 3 weeks ago I feel unhealthy and visit the doctor. My blood pressure going high to 190 - 120 which is strange to me. I start practicing fasting 12-13 hour from 8 AM to 8 PM or 7 AM to 8 PM with very wonderful result. After 3 days the blood pressure going down and down. Today the result is 135 - 95. I will continue learning to practice autophagy since I believe the body have been designed to auto healing if we restore the metabolism process.
