I’m not convinced your MODY either. Type 1 can come on extremely slowly and the time it takes to appear can depend on a person’s lifestyle and diet, and even once it has been diagnosed, people can have a long honeymoon with very small amounts of insulin. Please, please don’t take this the wrong way, but I think it’s probable your restricted eating has confused things.
I think you need to eat normally and use the appropriate insulin to control your blood sugar. That is, if you, say, eat a normal breakfast of Weetabix, milk and a slice of toast, and your post-prandial blood glucose is 15 or whatever, then you simply need some bolus insulin before breakfast. Lunch - again eat a normal healthy lunch, and then a normal evening meal. Use as much or as little insulin as you need in order to eat normally.
Without proof you’re MODY, I’d personally be loathe to take Gliclazide because it’s not good for Type 1 and you risk squeezing the remaining life out of your beta cells. Not good.
As for Tresiba, certain insulins seem to become ‘fallback’ ones and so are automatically used when often a different basal would be better. I think you should ask for a twice daily basal eg Levemir. You may then find you only need tiny doses or even zero for one dose.
Be pushy
@EmmaL76 You don’t have to take what you’re given. Ask for a trial of what you want eg a 3 month or 6 month trial of Lev and Humalog or whatever. You’ve been muddled around enough.
As a reminder, my Type 1 onset was considered “atypical”. I also scored much higher on the MODY screening test than I presume you did. And yet I’m still Type 1. Type 1 can present in different ways. Over the years, I’ve ‘spoken’ to many other Type 1s who’ve had unusual onsets, usually with regard to the slowness of onset, the fact they still make some insulin, etc etc. Keep your wits about you, be pushy and assume nothing.
