I have noticed that with each pregnancy, it seems like I get hit progressively harder and faster by dehydration. For example, after an especially bad day or so, I had resting heart rate of 120+, and I find that I get "fuzzy brain" and dizzy and start to black out although I am probably only moderately dehydrated. I also find that the more I vomit, the more difficulty I have focusing my eyes and have a hard time talking. With my first pregnancy, it would take several days to get to that point.
Has anyone else had this experience? I have my next dr. appt. on Tuesday, and I planned on discussing this with him.
