Hi Mari - welcome to the club no-one ever applied to join! You'll soon find out that we have some very nice helpful members though - I should hope. First off though, you do have to remember that because we're not exclusively Type 1s, sometimes folk make suggestions which aren't exactly appropriate to T1. This can be a bit confusing sometimes, especially when the person they're trying to assist is still at the 'KISS' stage with their D, but until another T1 notices and corrects them well they didn't know that - so it's part of the learning curve for them, too!
Our DSNs should be like extra mates - like people we've known since we started school, who we can be 100% honest with, however only available during working hours so they do have their limitations
😉 and some of em aren't quite as 'specialist' as others. Mine told me the other week to increase one of my bolus doses by far too much and I thought at the time, blimey, that's a lot for me all at once - and I was 100% correct about that

- but if after this long I didn't know more about my own body and my own D than her, that's not exactly a surprise either. So I reduced the extra, and it seems to be OK now, but for how long of course, is anyone's guess.
That brings me around to the slightly wrong terminology you've used in saying you want to control your D rather than it control you. Oooh yes, of course I agree 100% with the sentiment but it's just that D cannot actually be 100% controlled (42+ reasons that might affect BG at any time) but it can rather be
managed successfully - so please try to think of it as management rather than control, if you don't want to be disappointed.
Jolly good luck with it and as soon as you're ready to ask questions, fire away.
