So dehydrated can’t sleep

Lindsay

I know, have to drink more water. But I am drinking so much damned water and still keep waking every couple hours with my mouth wide open, completely dry and dry lips just dying for water. So that means basically I’m not sleeping. Helppppp!! I just want a good nights sleep. I’m so exhausted and wake up feeling like I have a hangover every morning. Tips?? 6w4days, third baby. Grateful at least I’m not nauseous all the time.
