Hi Cassidy @cassin24, in what phase is the moon? I usually don’t blame things like the moon, but I have just gotten through almost exactly what you are experiencing. During the period 03 Jan to 07 January I had BGL ranging from 160 to 350 mg/dl [8.9 to 19.5 mmol/L] even after increasing my pump basal to sick-day [+25%], eating practically nothing and taking correction bolos several times each day.
Turns out I had a couple of incidents converge. a dislodged canula, a crinkled canula and “suspect” insulin. Even after replacing everything I remained High" even with correction bolus [using needle and syringe] so I reverted to something I don’t recommend unless you are being VERY observant and have a knowledgeable person nearby. An endocrinologist had instructed me in this on a prior occasion.
I took an unusually large bolus with a needle and syringe and watched [constant CGM and BGM monitoring] my BGL slide from 367 to 100 mg/dl [about 20 to 5.5 mmol/L] over a period of 9 hours. This method can be dangerous and should only be done when you are not alone and have some one who can remedy anything that might happen. Be careful.
