Did the vet give you a prescription for Hycodan? It's a synthetic codeine cough suppressant. Sometimes codeine is better at nailing a cough than the over the counter meds. If Sherman is achy from coughing the codeine might help with that too. (You all know what I mean - when you get a cold and you've been coughing like crazy, your muscles just hurt from so much coughing.) I'm sure it will make him more lethargic but if he needs to rest, that might not be a bad thing. Sherman, sweetheart, I'm so sorry to hear that you've been sick. I'm glad that your Mom was able to find a veterinarian who could see you quickly, and I hope that you will feel much, much better P.D.Q.!
