Bone broth from Walmart, cook some veggies in it and strain, some protein water as shakes are thick and sweet, crystal light, sf popsicles. You will need to hydrate as much as possible. Premier protein shakes are tolerated by many of us after surgery but don't overstock. I also tolerated Isopure ready-made blue raspberry or punch diluted w crystal light. Most important is hydration as it takes all day long sipping. You will not feel restriction or fullness until you get to real food so don't be alarmed that even thick liquids aren't restrictive. What you will feel though is inflammation and swelling, so sip slowly. You may not be hungry or sometimes hunger is acid reflux. You will however feel the effects on your body from lack of nutrition, it will be fatigue, no focus. Drink something and take a nap. Light headedness is a sign of dehydration, do not dismiss this - push liquids even if you do not feel like it. Walk off the anesthetic, the only cure for that and the gas. You might get constipated, ask doc about what to take - I would ask now and get some items.
Good luck.
