about 5 and1/2 weeks.
I am almost 9 weeks and it hasn't gone away. it is hell.
the first week and a half were constantly awful. after that it was a little better.
now I have some moments where I can eat and some moments where it is awful.
I was hoping I wouldn't have it (my mom didn't) but I guess not.
I told DH he better like this kid because I don't think I can do this again. :-)
