on account of your hypo awareness, which the Libre wont help with....
Although libre doesn't have alarms, it is still incredibly useful for hypo non-awareness.
Daytime, scanning is easy enough, I tend to do it pretty frequently just because it's there, in much the same way that people chew pens. You can get a real sense of dropping levels just by regular scanning. I've caught plenty of potential hypos that way just by waving it past my arm and getting a heads up on levels dropping and taking a few grams. Lack of alarms in daytime aren't a problem, because you can see the results anyway and do something about it long before an alert would trigger (depending on where the alert is set!).
Night time alerts, sure, that's the main thing missing from libre at the moment. I would like that, and I'd vote dexcom and medtronic up on that account. But, even then, I reckon that what happens when I'm sleeping is influenced a lot by what has happened in the last six hours before going to bed, which libre will tell me about, so I've been able to kinda steer things a lot from that. I'm not getting night alerts, but because I can make better judgment calls from what I'm seeing before I go to sleep, it's not that much of an issue.
I've lost a lot of hypo awareness after thirty years in - don't get much adrenalin cold sweats or shaking thrown in as a warning, signs are much more subtle - but I can put my hand on my heart, swear an oath or whatever, and say that in the ten months I've been using libre I've not had any hypos worth worrying about. Despite lack of alarms, I've been able to pick them up in early stages.
