Hydrochlorothiazide
"I've been taking a HCTZ in combination with blood pressure medication. So far it has worked well for water and salt retention. My blood pressure has come down from its highest point of 220/120 which is insanely high, its now at 140/80. Only complaint like the other users is constant urination at night. During the day it's not noticeable but right before sleep I'll go about 2 to 3 times."
