i prefer koolaid. mix it with splenda = zero cals, zero sugar. several things can make you retain water, menstral cycle, certain AAS, too much sodium, lack of water consumption etc. 35mg of sodium is not a lot especially if your drinking plenty of regular water (probably more like 35*2.5 serv = 87.5mg or 35*4serv = 140mg, even still, the sodium is moderate, but can add up if you drink many of these). if you drink more regular water it will be flushed, so i dont see how it can contribute substancially to water retaining. you can gauge your sodium concentration by looking at your urine. usually if its dark, you have a lot of sodium in your system. plus, if it curbs your sugar cravings, i dont see why not, it sure as hell beats a piece of chocolate moose, just dont overindulge on the propel, those cals, sugar and sodium can add up.
