Lisinopril
"On lisinopril 10mg & bendroflumethiazide 2.5mg. This dropped my blood pressure from 165/110 to 140/90. I had been avoiding increasing the lisinopril to 20mg. In addition to family history of hypertension, I was 115kg (I'm 6' age 47). 
Gradually over past 7 months got weight down to 80kg. Diet, regular cardio (cross trainer) and anaerobic (weights). Stopped the diuretic. BP 130/80.
Initially side effects were persistent, dry coughing but that stopped when I quit smoking. Occasionally a little light-headed a few hours or so after taking. No other problems with lisinopril. 
The diuretic was a pain, getting up 2-4 times at night for a pee.
Can't recommend enough the combination of weight loss & exercise"
