mid night vomiting

Hi all.
The past two nights, snuggy has been vomiting in the middle of the night. During the day he is his normal self with no vomiting, but while we are all sleeping, he practically explodes all over my floor.
The only difference I can see in his daytime behavior is that he seems to be more opposed to his amps and pmps testing. He still is not agressive, just MUCH more wiggly and clearly opposed. I'm also having a hard time getting him to bleed so have to poke multiple times even though I'm hitting the vein with every attempt. Perhaps he is dehydrated?
We have a vet appointment in 20 minutes, so hopefully we will find answers.
Thanks all

 

Well, just back from the vet and boy are we on a diagnostic adventure! The vet thinks snuggy may have irritable bowel in addition to his diabetes, as well as the possibility of another condition affecting his digestion. They ran some labs and will call be later with the results - I'm hoping its not too bad of news!
