I Am 74 Yrs And Have Been Having BP Issues.

I am 74 yrs and have been having BP issues. Hard to control the BP at times and it always riseses at night. By 9p.m. It will start to rise and go up to 170/80 and even higher at times. I take a 0.1clonidine but it does not lower it even after an hour. Does not go down till I get up the next morning and take my meds. 40mg Lisinopril
6.25 Coreg, and a 0.1 clonidine both morning and evening.
