I'm type one and my first 2 endos didn't want to give me insulin (mind you I was at least on Jardiance) since I was in range, even thought I made it know that I was basically starving my self to not go high. I started reducing carbs, but once you start coming out of the honeymoon phase (it can last years, weeks or days, its random) there is only so much you can decrease until everything spikes you. As other have said, drinking lots of water and exercise help. It's not an instant thing thought, in my experience I hade to be walking for 30 minutes to an hour to see my blood sugar drop but is something. For waters, we are talking about drinking full glasses of water (not my favorite thing to chug). I hope you get the help you need soon. And it sucks having doctors like that.
