Managing Mounjaro with T1D

This is my first Reddit post ever so forgive me for formatting issues and everything else.

I’m a T1D of 11 years. I’ve been struggling with taking care of it for most of it because I’ve always struggled with immense weight gain when I took care of my blood sugar and steady weight when I had high blood sugar and ketones 24/7. I’m talking BAD, never checked my blood sugar and only took my Tresiba and ~13 units short acting at night before bed. This went on for about 7 years.

I’m finally getting back on track and my doctor prescribed me Mounjaro so my weight gain wasn’t so uncontrollable, turns out I have some insulin resistance too, but now I’m having issues taking care of my blood sugar. I know it’s because of the slow digestion so my blood sugar doesn’t react as quickly to carb intake. But because I hardly even knew how to take care of my blood sugar initially because of lack of experience I’m experiencing more issues now.

Basically my question is for anyone with experience managing both t1d and Mounjaro, what did you find worked to manage blood sugar while its reaction to carbs feels so sporadic? Any advice or insight would be very much appreciated.
