@CaraOC it's way too soon for you to be taking Advil no matter how you take it. Advil is an NSAID, and all NSAIDs are hard on the lining of your stomach. right now your poor stomach (what's left of it) is still very much in the healing process and the last thing you need is something that will irritate it further and interfere with the healing process. Hopefully your surgeon prescribed something that doesn't include any NSAIDs for you, or you could try Tylenol, which is not an NSAID if you need something over the counter.
As far as eating goes, I also had a bad time for several weeks, so I can relate. Egg drop soup is a good choice, I also tried Progresso soups but without eating the solid stuff they contain. The broth was so much better tasting than plain chicken broth, and not at all sweet. I absolutely could not deal with jello. Maybe a little soft boiled egg, or scrambled egg would do well for you. Don't worry about how little food you are getting in, that really doesn't matter at this point. If you can stay hydrated you are doing fine.
