Usually I drink a lot of water during the day but more towards the night I slow down cause I always have to pee, but usually I wake up around 3 or 4 every morning with a really dry throat. Does this usually happen during pregnancy? I figured it like this, the baby continues to take my fluids while I sleep from me and it makes me more dehydrated, I am not sure but its so annoying having to get up when you really dont want to and walk clear to the other side of my house just to get some water!
