The Honeymoon period can last a long time, over 8 years plus. There are theories, that starting insulin helps protect what beta cells you have for longer. That low carbing, puts less work on the beta cells so they work better and last longer too.
I have heard of people going off insulin for a bit when they have changed to low carb, I don't think that lasts for that long, but I'm not sure I ever kept track. I am of the mindset that you might as well start using insulin sooner versus later as you are going to have to have it at some point. You might as well start learning how to use in tiny amounts first and learn it's effects when you have more of a choice and it's not as critical. It makes you more comfortable with using it when eventually you have to rely on it for anything you basically eat. Even a bowl of broccoli. That's just my opinion though. Some people just want to avidly avoid it as long as possible.
I was on tiny amounts of Humulin M3 8 units down to 3 (?) for 3 weeks when diagnosed and my bloods were in the high teens but I was hypo-ing in about 10 days, so I came off as it was a ridiculous waste of time, energy and stress. I don't want to go through all that agro with the DVLA again until I have to, don't want to be checking my blood every time I get an unexpected call to go get the kids from school, or I want to spontaneously pop to the shops and having to wait until I am at the right level, and I definitely don't want to be pumping myself full of anything I don't need (yet).
I am holding out that by the time I need insulin the technology and NHS budget will mean I don't have to turn my brain into a pancreas, I have enough going on in my life to not need to do that too. My HbA1c is non-diabetic, so I am happy to eat well and low carb (sorry, big yogurt, meat, cheese and egg eater here), and avoid glucose-raising stress for as long as it lasts.
Just now my Libre says I am at 3.8, It'll probably adjust to about 4.5 in 15 minutes, as I've just been racing about before coming to bed, but no way would I want any additional insulin working it's magic on me too!
I know this forum and elsewhere are full of heartbreaking stories of not being able to get dosages correct, extreme hypos etc (and I know there's not much of a call for multiple threads on how folks got their carb/insulin ratios spot on) but the longer I can live without any complications like that, I'm going to grab it and run! We're all different, but I know I am always one for the easiest route; I breast fed all my kids, 'cause who has time for sterilising bottles, especially for twins, if they don't need to!!
TMI?
