Blogging Baby points to a SanDiego Union-Tribune article on "morning sickness" and hyperemesis gravidarum. The article mentions that author Charlotte Bronte is believed to have died from HG. Didn't know that.
As for me, I still feel a little nauseated in the evenings and occasionally in the mornings. It is a little anoying, as I remember it being all gone by this point in my previous pregnancies. However, it is nothing like the debilitating nausea of the last 3 months, so I'm not complaining. I am actually enjoying food now, even craving foods sometimes.
