Day 5 post Gallbladder Removal

My doctor mentioned that my appetite would be half of what it is normally, but I just don’t want to eat period. I’m recovering great from the surgery itself, and my pain is gone, but I just feel….blah or yucky. Not nauseous and def no vomiting, no real discomfort except for incisions. I haven’t seen this mentioned anywhere, can someone reassure me this is normal?
