One more suggestion. Then I'll quit..I promise.
I know an e-collar is out, I hate the things anyway. A friend of mine used her cervical collar, (foam neck brace) on her dog after she had surgery almost like Pepper's. She had free range but could not reach her side to lick. The collar can be bought at any drug store and is one size fit's all with velcro.
Yes, they do look funny but it is totally functional and so is your pet.( Pets can care less about looking funny) I am sure she is getting very tired of all this. Not only the attitude get's worn down but so does the strive to be alive.
She is eating and that is a good thing.
She may also be as little "unlevel" being use to carrying extra weight on one side and now it's gone.
Just my thoughts.
Be The Kind Of Person Your Dog Thinks You Are.
