My conclusion from the number of responses received on my last post regarding residual nausea (that is, none!): Post-hyperemesis residual nausea or being nausea-prone post-hyperemesis is extremely rare! Hurray!!
Thus, those of you out there suffering from hyperemesis don't need to worry - it looks like most hyperemetic mothers bid their nausea farewell at baby's birth (or before!).
On the flip side: Well, Anna, looks like it's just you and me! LOL!! :)
