Before I got the pump, I was combating DP by taking a small mixed-nutrient snack (low-carb ice cream) at around midnight every night. This helped me keep my mornings no higher than 110. Problem was that despite that, I was also going low twice a day – at around 4am and at 5pm. Changes in my basal insulin helped, but only for 2-3 days, after which I was back to the same pattern. My endo also thought that my high BGs was a counter-regulation (Smogyi effect). I DO wear a CGM and saw that even on those nights when I did not have a low, I still had high numbers in the morning (when I skip that midnight snack); however, my endo wouldn’t accept my explanation.
Maybe it’s for the better, though - to avoid those lows, he got me on a pump. The pump has been wonderful - within 2 weeks, I all-but eliminated those daily lows by adjusting basal rates. It has also added a lot of convenience, though that was not part of the reason to get it. Are there issues? Sure, but I think it’s been a good trade off, so far.
