With DD I was naesous (no actual vomiting) day and night from about 8wks through non stop till 14 weeks. It was dreadful - i would spend half the day over the toilet willing myself to throw up just to get rid of the awful sick feeling.

This is exactly what I had with DS! And also lasted 14 weeks. I was pleased to see the end.

I hope it eases up for you real soon. (MS is not nice at all)
