For nutrition, I'd focus on supplements like Ensure, or whatever you think is palatable. Those provide balanced nutrition and areeasy to digest, without overtaxing the upper GI. You don't want to take anything to speed up or slow the gut right now, since it is not synchronous. Even narcotic pain meds are counterintuitive at this point. Meds to tone down nausea are OK though.
Keeping the activity level up is important too, but you are already doing that. If you have not had your potassium levels checked recently, that should be done to rule that out as contributing to your slow upper GI.
You'll get there, and hopefully without TPN.
