Thank you for your kind response to my post! As to the devices I mention: The "pod" I refer to is actually my Omnipod insulin pump. In the normal course of events it doesn't have alarms except a very quiet one to remind you it's about to expire. The one I had on yesterday was faulty. Depending on the alarms you set yourself on the Libre it will alert you to the fact your BG is going low, or high, or it's lost contact with the reader/phone you use with it. I only have the low alarm set. This alarm is immensely useful as it goes off when my BG falls into the low 4s. This enables me to take some Dextro (hypo correction of your choice) to ward off a hypo. In the last 90 days I have 0% time in the red (under 3.9). I wouldn't be without a sensor now. I personally find it extraordinarily accurate and only finger prick once or twice when I apply a new sensor. I regularly dose off it.
As to how much use it would be for you as a T2 I'm unsure, but it would show you patterns in your BG and would show you how different foodstuffs and exercise affect your BG. e.g.. I ate a potato and I rose 3mmol or I ate a potato, dug out some footings and I didn't rise at all - sort of thing.
FWIW you can have a free trial of a Libre 2 see

Once again, thank you for your generous response
