Been there. PEG, although not a pleasant thing, works. Two thing come to mind. First is hydration. If your not eating your probably not getting enough liquids as well. The PEG should solve this problem as water is pretty easy to do on the PEG. However, for the next day or two getting hydration through arm is something you should consider. A least for me, a couple a bags of water/saline had huge short term benefits.

Second, food or formula is another thing, Boost, or any other high cal supplement is basically vegetable oil and corn syrup. Your stomach may not like this mysterious liquid that just showed up in your body. I probably through up 12 times before I learned to go very slow. Do not just Bolus a can of food in a minute or two. Go slow, Maybe a can over hour. Don't be tempted to just jam it in. Having a bucket near by, just in case, is also a good idea.
