Have High BP. Why Was Urine Flow Slow? Are There Medicines?

hello, my name is romualda estoy. i am 44 female. myquestion is. Is it right to take 4 types of meds even if my pressure is controlled. last visit was on may reads 80/72 -good..i was taking drugs since 2002,and for 8 yrs. no results. up n down. when i include taking food supplemnets i notice my high blood presure gets better. my dr. does not change/remove the amt. of drugs i drink.so disgusting. i am tired of taking it. i know my body. she said if she takes some of it it might raise the BP #.she said it might even damage d kidneys..when i was on it my urine flow was low. when i have FSupplement i am satisfied. the flow is so much...my wgt. is 156# i have to loose some..sorry, just sharing.atenolol-100mg;losartan-100mg;hydralazine-150mg,3x/day-amplodipine-10mg. I am wondering why ther is no one big amount of meds, just to take care my problem not 4 kinds. so expensive to pay...thank you..looking to read your thoghts..i want only 1 meds....
