The alimentary canal starts in the mouth, and ends at the "back door" of your digestive tract. It makes all the sense in the world that when part of that canal system is traumatized, the whole tract feels it. Also, your stomach has been through a major revision...stretched and wrapped and stitched. Since your stomach isn't feeling perky, your appetite suffers. It's all part of the healing process, and that hearty appetite will return, once things have a chance to heal.
It's great that you're a "get going" person under most circumstances, but when it comes to healing after major surgery, it's better to slow down and give your body time to heal. You'll be able to get going soon enough. It's important now, that you listen to your body and relax into your recovery.
Bill, another moderator here, always says it's a marathon, rather than a sprint. You'll be recovering for a year from this. Of course you won't feel like you do now in 8 months, but your body will still be doing the job of healing, and your upper GI tract will be adjusting to the changes that were made.
I don't know if you saw my recovery journal, but here's the link, just in case:
It's not a bit uncommon for surgeons to inadequately prepare their patients for their recovery. I suspect they don't really know the full range of the experience themselves...sure, they have patients who call to report bothersome or worrying symptoms, but as a whole, they really don't know what it's like. They know in theory, but not what the experience is like in reality. That's why this forum is so helpful...others who have "been there, done that" are just a keystroke away!
Glad you've joined the forum! It's a great place to be during recovery.
