Thanks for all the replies, ladies. I really appreciate it!

She is going through hell. She just wants it to be over. Sister and I had discussed the fact that headaches and vomiting do not make for a life-threatening condition but Sara makes a good point, sometimes neuro conditions can come on quickly...

Also, the neuro has indicated exactly that - they are not sure how she will cope with natural labour, given how much stress her body is under, not to mention the mental stress.

She's going public - can she request an appointment with an Ob?
