My baby MILO (RIP) was in remission for years. He was diabetic the first time for about 1.5 years when I found these boards. Got him in remission for several years, then in December we aren't sure what happened but he became diabetic again. We could not get him regulating. In the end he had some sort of reaction to the meds during a teeth cleaning and passed away (found out he had a tumor at the base of his brain too).
It takes work but it can happen. I know even if he had stayed on insulin and hadn't been in remission for those years he still could have had a good quality life. The people here are great support and sometimes following their advice (even if different from vet who might not know much about diabetes) helps.
Good luck...
