Dawn phenomenon? Are you on a CGM? I found the closed loop system with the Dexcom CGM and the Tandem pump have really helped my levels.

My first thought is Dawn phenomenon too. It comes and goes for me. I try to eat and take insulin ASAP after waking. I've heard of people taking a shot before they actually get up, too. Another term is "Feet on floor", so they don't mess around! I use the Libre CGM (but technically mine's not a CGM), and it's been helpful in pinpointing when my glucose starts to spike. Oh!! It's also possible you are going LOW in the night, your liver kicks out some glucose, and you catch it after the rise.

This has been a thing for me for sooo long and my Endo kept lowering my overnight basal dose insisting it was a somgyi swing but 90% of the time it wasn't... I can tell when I fell asleep when I look at my dexcom because I'll be stable around 150 and all the sudden it starts to climb and I wake up at 350 feeling sluggish/nauseous af

Thank you all for sharing. I believe it's a mixture for me. I don't have a consistent use of a libre atm. Right now im poking my fingers. I guess you all are just too sweet for your own good. 😉 I hope I can get this managed enough to feel functional and not drag. Thank you

My endo has told me that sometimes the body thinks it's dropping so it release a chemical to help bring the blood sugar up. Not sure what the term is for it but she recommends eating a snack before going to bed so your body doesnt release the chemicals i guess. Dont know if that made any sense but. TLDR- Eat something before bed to prevent high glucose in the morning?
