Type 1 Dexcom and perfect levels

Have you come across the term “foot on the floor”? It’s when our system detects we’re awake and dumps a load of glucose from the liver to get us going - it’s a cortisol response that happens as soon as we wake up. I need to take 1.5-1.75u Novorapid as soon as I wake up to stop a ridiculous rise of 2-4mmol, pretty much. But only on days when I have to be up for something like work. Other days, I watch my levels on my watch like a hawk, and as soon as I see my levels start to rise, I’ll take the dose for it - it doesn’t always happen on non work days, and I’ve given myself a hypo more than once by taking insulin and then it didn’t happen.
