I can vouch for the stability of Tresiba/Degludec, only 1 injection a day and it lasts around 36 hours, it reduces night time hypos due to its stability, very flat profile. I was on this before I went onto the pump and recommend it.
I have been diagnosed 4 years and have had background retinopathy for the past 2 years, I believe my issues were bought about due to the time I was undiagnosed although I was very poorly for a week and onset very sudden I think I went a long time undetected, I read Bernsteins book and although adopt low carb pretty much 5 days a week I relax a little at weekends and will eat choc, have a glass of wine, but have stabilised my bg levels much more, at one point early on I was yo-ing a lot high and low, low carb has helped hugely, I have only recently had my eye test come back as normal. The book to me was a revelation in self management, and comforting also to be written by a type 1 who is now in his 80's living a complication free life.
Watch out for hidden carbs tho like milk, and protein also converts to sugar so you still need to inject some quick acting to cover it, there isn't necessarily a free lunch with lo carbing
