hmmm open loop diuretics are never good....its true that the spelling of lasix is because it LAsts SIX hours in the system.
pottasium sparring diuretics are more favoured i think but you have to have someone who knows what you have taken because if you collapse with severe cramps from over use, the first thing medical staff will do is pump you full of potassium intravenously thinking its what your lacking, then hook you up to a IV full of it....uh ohhhh......Potassium in high doses is lethal.
Open loop sides
Hypervolumia (too much water in the blood) Strain on the heart due to increased volume of water being pulled from the tissue.
Hypokalomia (too little potassium)
Metabolic alkalosis (acidic blood)
Hyperuricemia (level of uric acid in blood where you produce more than your pissing)
