I think I'm drinking more fluids now than I was when I was in heavy training. According to my doctor that's normal since your blood volume is increasing. Man so so thirsty! I wake up with a glass of water, milk and oj with breakfast, then a glass of water with my prenatal vitamins, then I carry a water bottle around with me all day and fill it up several times (usually put Nuun in it so I get some electrolytes), and then (even though I shouldn't because I'll supposedly pee more) a glass of water before bed. I've noticed no more or no less nightly pee breaks whether or not I drink a glass of water before bed.
