At my latest prenatal appointment my OB told me that I have been very dehydrated and that I need to drink more water. Ok cool. But she said I need to be drinking a gallon of water a day. I have been trying very hard to do that, but I can't even drink a half a gallon! Not even when I start as soon as I wake up and drink throughout the day. I'm sorry, but a gallon of water is just insane for me and it's making me sick forcing myself to keep drinking all of this water. Is she out of her mind, or is she right?
