when I started exercising my total daily dose went down 40%! needless to say I needed to do a lot of tweaking. as allgr8 mentioned both my basals and insulin to carb changed. I couldn’t have done it w/o my doc though. You can try (if you haven’t yet) eating a snack before bed but that would be for the mean time only, your doses definitely needs some adjustments.
Love the feeling when lowering my TDD, I have a bit of an obsession with it, I check that screen daily:o
