Tastes awful and something about it makes DH and I swell like crazy. So we buy the spring water packages onboard (if we aren't staying concierge). We cannot be bothered to carry a case or two of water onboard.
And I assure those who are stretching their fingers to type that if it were the food then we would swell no matter what. We are still eating lol. But when we drink the ship water we swell (it's one of those lovely sensitivities we have in common), and when we drink spring water we don't.
We are not the majority, and I hope you do just fine and like the water.
And we don't know if it's that maybe "desalination" doesn't mean "UNsalination", or if the process takes out ALL electrolytes and our systems can't handle it, or something I haven't thought of. I just don't know the "why" of it.
