The LibreLink app allows me to use different alarm tones for lows and highs, and I'm _still_ getting alert fatigue. To the point that my wife needs to ask "is that your phone telling you you have a hyper?" for me to actually start doing something about it, sometimes.
I disabled all the alarms on my libre 2 (which incidentally is why I won’t be going to the 3). Doing so explicitly puts the responsibility back on me where it was all along.
