Each time I am pregnant I get so, so thirsty. Not "ooh I fancy a lemonade" but "oh my god I NEED two pints of water immediately and I will mow you down if you come between me and the kitchen tap".
I've mentioned it a few times to various midwives and been vaguely told that it's fine, so I'm not particularly worried.
Thought I'd put it before the collective wisdom of mumsnet and see if anyone could shed any light. Is it just a pregnant thing?
