The cause of his tail biting is most likely being alone,
Chewing on his tail is most likely due to an injury to his tail - not from being a single glider.
Please do take him back to the vet as soon as you can. The vet may need to x-ray the tail to see if it is broken.
The e-collar should have had moleskin padding around the neck area - and you should have been instructed to check the condition of his skin around the neck area frequently.
If he is chewing his tail again, you can use a large milk-shake type straw cut down one side so you can open it and put it around his tail. You can secure it with some tape after you slip it over the tail. This will keep him away from chewing his tail temporarily - but you will need to keep a close eye on him until you get back to the vet - ASAP
I hope you can get to the vet early tomorrow and that your glider begins to heal quickly.
