How much volume are you drinking? I do not agree that there is no limit on how much you should drink daily. You can deplete minerals and especially potassium with too much water. If you are drinking the approximately 64 ounces recommended, that should be enough. We are all different in our needs. If you are just not accustomed to drinking that much water, you will get used to it as you go. Try to sip it through the day and not drink large amounts all at once. That might help.
