Morning Sickness?

My wife cannot do anything normal.  She is experiencing the usual nausea and upset stomach that you hear pregnant women going through.  However, she's not experiencing it in the morning.  She's getting it in the afternoon!

And every once in a while, just to throw me off, she gets sick in the middle of the night.  She wakes up from a sound sleep to throw up at like 2:00 a.m.  It's disconcerting, because it's chaotic.  I can't get into a stable routine or expect it.  It crops up at the most random times.

I know she's doing it just to be different.  She wants the spotlight to be on her and have a unique pregnancy.  I'm not sure how she managed to do it, but I know she altered her chemicals somehow to change the timing of the sickness.  I mean she is a geneticist after all, so I wouldn't put it past her to do something like that!
