hi every body is different and response to medication varies from body to body ,you are in stage 1 systolic and stage 2 diastolic hypertension,theoretically to revert you back to 120/80 is not possible without medications but the doses of these medicines can be tapered off depending on the response given by your body losar a contains losartan and amlodipine (you are on two anti hypertensives) as per your body response these doses will be tapered off and physician will try to settle you on one anti hypertensive. follow life style medication 45min of strenous exerciss daily low salt diet avoid fats and oils like butter peanut oil. try this for atleast 3months keep a record of your bp every 3rd day. and lets see how your body responds to it ,it will take atleast 3months to see the effects there are some side effects of these drugs but when we look at prons ,cons can be neglected ,most of the anti hypertensives are very safe these days and can be continued for life
