Bobby - We have a ferret with insulinoma also. She was diagnosed about when yours had surgery. We started her out on just the insulinoma elixir and she did great on only that for about 6 months. After that, we finally had to put her on prednisolone and proglycem. WE started her on 0.02cc (yes, that little, we have to measure it with a tuberculine syringe) of each 2 times a day. She did fine with just that and the elixir for a long time but we have slowly had to increase her to 0.12cc. She's doing great on the meds and about 2tbs of the elixir 3 times a day. If you need a copy of the elixir, I can send it to you. The ingredients are somewhat hard to find but we have been able to find everything but one ingredient in our local grocerystore and pet store. Though you might need to find a natural/health food store if you don't have a big grocery with a vitamin section. Take care, Steven [Posted in FML issue 1982]
