Forget "Midnight snack" I'm eating at 4am!!

 I'm 10 weeks and im afraid that if this is happening now, mah figgah is DOOMED. Im a downright hog!!
Now I always snack on a little something right before bed. ( By snack I mean I have a second helping of whatever I had for dinner ) 
But last night I woke up so terribly nauseous and I just knew it was because my stomach was empty. I tried going back to sleep but I felt too sick, so like a soldier I made myself a fat-ass ham sandwich. Not a saltine, not a slice of bread or swig of mineral water- a lettuce, tomato, mayo friggen ham sandwich.
It was awesome. I slept like my baby...and yes, I had breakfast.
I have Digelsis but it makes me waaaay to sleepy the next day and the nausea comes back even worse. I'm expecting the nausea to get better, but this kind of eating at 10 weeks??? Yikes.
