nausea at night

I am 2 1/2 weeks out from RNY, and have been waking up with mild nausea in the mornings. Not sure why, and it just started. Does anyone have any ideas?

Dehydration can cause nausea.  You might try having a bottle of water by your bed a sip a little when you wake up in the night. Make sure you hydrate well before bed. 

Thanks a lot, I knew I had not drank anything I am not supposed to, but I am having a little trouble getting thirsty at night. 

I know of several who would keep a glass of water next to their bed early out so they could grab a few sips in the night or first thing in the morning before they even get up.
