Sounds like a good plan, I wouldn’t correct below at least 10 either, but you have to do what works for you.
We all know that diabetes is a tough beastie and you have to work at it to stay healthy. But getting perfect numbers all the time is pretty much impossible with type 1, no matter how hard you try, and you could send yourself a bit doolally trying. (I know, I’ve been there and done that when my daughter was first diagnosed.) Getting near perfect numbers is great for your overall health, but if that’s all you ever think about and you never allow yourself to relax then what’s the point, you have to enjoy life too. That’s what a DSN told me. On the other hand, if you allow yourself to relax too much and get too much of an “oh I’ll sort it out later” attitude then you aren’t really looking after yourself properly and are quite possibly storing up nasty problems for yourself later on. Finding the balance between those two extremes is one of the hardest things with diabetes, I think, and where you position yourself between them might not be the same as where my daughter and I are, or anyone else on this forum. We try to get things right as much as we can during the normal daily routine, but aren’t afraid to have treats sometimes without worrying too much about exact carb counts and if we get the occasional day where it all goes wrong we just think “oh well, try again tomorrow”. As long as we aren’t getting those days every week it shouldn’t make much difference.
