I believe you have opened multiple questions about Azzy.
I said in one of those previous questions that this sounds serious. You said on your other question that his gums are pale, and that is a sign of possibly serious illness, such as anemic, infection, internal organ dysfunction.
If he is not eating, only drinking, that also indicated serious illness. Cats sometimes only tell us they are sick when they won't eat their food.
At home, all you can try to do for him is keep him hydrated with broth and water. What he needs is a good physical examination: feeling his pulses, internal organs, lymph nodes; taking his temperature; listening to his heart and lungs.
The dilated eyes could be from contact with a toxin or drug. Sticking his tongue out of his mouth also indicates possibly serious illness.
You said that you will do whatever it takes to help him; what he needs is to see a veterinarian, have a good physical exam, and see if he is anemic, has a fever, or has any dysfunction or illness of his internal organs. If this were my own cat, I would not be trying to treat him at home.
Please continue to repond here and do not open more new questions.
Let me know how he is doing and what else I can answer. Rebecca
