Ivchister,
The only thing i can add to this discussion would be (I have to say it) a veterinary diet, I looked at Royal Canin Hypoallergenic Hydrolyzed Protein It is available in both wet and dry versions, if what you are currently feeding does not work.
You can get it online with a prescription from your vet,
I do hope what you are feeding works.
Best of luck
