Hi
@kh89 ,
I completely understand your hesitation, and you have been doing your research. Metformin can cause gastro-intestinal upsets, which is much less likely to happen when you don't take it on an empty stomach, so yeah... With breakfast and dinner would be an excellent plan!
That said, what metformin does is mainly make your liver dump less glucose into your system (it does that in the morning to help you get your day started, when you're stressed so you have energy to flee, for instance), and it makes you a smidge more sensitive to your own insulin. It doesn't really do a whole lot about what you ingest, and that's where the highest blood sugars usually come from.
So here's the thing... You're just barely into the diabetic range. A few small changes in your diet could well bring you back down to the prediabetic or even normal range. It's carbs you can't process well, being insensitive to insulin as a T2, so... Have fewer carbs. Sounds simple, right?
https://josekalsbeek.blogspot.com/2019/11/the-nutritional-thingy.html might explain things some in that respect. Just, you know... It's a scary time and a diagnosis no-one wants, but now you know what's going on, and you can do something about it. Knowledge being power and all. Main options being a change in diet, medication, or a combination of those two. You'll find something that suits you and your situation, I'm sure.
Metformin is a very mild drug, and not everyone gets glued to the loo, just a fortunate few like yours truly. And if that happens, you can always ask for the slow release version, which is kinder on the gut but not the first version of choice given by the GP.
You have a say in all this.
Good luck,
Jo
