My hubby has a jejunostomy feeding tube and when he was on it 20 hours a day, the basal insulin (glargine) held him at very reasonable/ low BSLs. Even when he ate spasmodically, he didn't need to inject at all. He is now eating regular meals and the need for rapid insulin has increased to "normal" levels. We are hopeful the feeding tube will come out soon.... it has been in since May. Do you have any hope of getting off the PEG?? I so hope so.. tube feeding is not easy.... I do know that continuous tube feeding (even if it's only 12 hours/day) and a good basal insulin dose will keep things in check from the diabetes side of things.
