Hydrochlorothiazide
"I have taken hydrochlorothiazide for almost 20 years.  Had to increase to 50mg.  Never really brought my blood pressure to normal until it was taken in conjunction with Lisinopril.  My blood pressure is perfect now.  HCTZ is great for water retention.  Need to take it in the morning as in the evening I was constantly waking up to relieve my bladder."
