Thoughts and prayers. I experienced something similar back in May. Nothing would stay down including water. The IV helped to rehydrate me but it took a couple of days to get a medication combo that worked. While it was a rough couple of days, both baby and I emerged unscathed. I was pregnant at the time and my DD was born 07-01-2014
Ugh poor thing. Hope she feels better soon and they find out the cause. I had this once, but I was 40 and had the worst migraine of my life. Probably not the issue here.
