Just curious if anyone else experiences this. Last night I treated myself to a large pizza. I used to be able to perfectly control this with bolus shots but now I find it more difficult. Anyway, long story short, I spent the whole night between 12-16 mmol. This morning I woke up feeling bunged up, groggy, sore throat, headache, just generally ill. I've noticed I've had this same experience before after a night of high levels. I'm not sure if I am getting a cold or if it's just my body reacting to the sustained period of high levels. Anyone else experience anything like this?
