After about an hour of sleeping, I get a feeling of nausea and have to get up. I can sleep fine sitting up in a chair, but that gets old. I do not eat at least 3 hrs before bed and then it has been only liquids.:tired I'm only 4 days out and so far I have had no problems from clear liquids to smoothies to applesauce. No pain. No other problems. If only I could sleep in bed:cry
