So we just got back from the vet. She said so far I've done everything on my own right, such as changing his diet to a single protein source. She agrees that these episodes happening like clockwork isn't normal so she suggested some blood work. We did everything from a CBC to a GI panel which would include pancreatic and liver enzymes and also check his intestinal flora. He also got a shot for nausea; it seemed to help. He ate a few pieces of kibble when we got home. I'm keeping my fingers crossed that I will get an answer as to why this is happening to my boy. I can't stand seeing him moping around here all day
