With dogs a vet will induce vomiting before two hours of ingestion has passed
Also Giving charcoal to absorb toxins
If your vet woln't (can't) do things like that
Dark chocolate has high levels of toxins
He should be kept cool and hydrated
Did the vet offer any advice at all
I would call (don't move him unless someone will see him)
Ask a few vets
If it has been a long time he will already have the toxins in his blood and their woln't be anything that can be done but treating symptoms vomiting (I don't know if sugar glider can)
Diarrhea
elevated heart rate
overheating
Labored breathing
Seizures
Are things to expect
Sugar glider have a fast metabolism so it should go threw his system quickly
If he makes it 48 hours I think everything should pass threw his system by thin I don't know if it could cause long term damage to the liver or heart you would need to ask a vet
Good luck. I always have mine with me and have wondered what if he tried to get at what I was eating (chocolate coffee ) I don't think I could stop him if he decided to get at it
