One of the slightly scary things about T1D is that at first you get a weird feeling when your blood sugar is too low, and you can notice when that happens. But if it happens too often, those warning signs stop, and you can get into a really serious condition without noticing for yourself.

The worst is during the night: You are sleeping, in a partial-dream, know you have hypoglycemia --somehow you know-- but you don't know for sure but it feels like something you experienced before, you do not completely wake up, dream somewhat lucid and are aware but you cannot decide to wake up and get something to eat but keep on dreaming and it's not a happy dream and keeps on going. Usually my dream-self starts screaming at myself to wake up. I've had that a few times and it's scary as [expiative here].

A CGM, app like xdrip and a smartwatch to display the current glucose value, trend graph and insulin on body has completely removed these situations from my life. As people normally check the time, you'll be checking the glucose value when walking outside

That's the glass half-full. If that works for you, then I'm happy that at least one of us has found a solution that works reliably.

The glass half-empty is...

I'd be much happier if I actually had an information device that I wore on my wrist that gave me all the data I need to manage T1D at a glance without igniting arguably the worst alert fatigue ever seen in healthcare when I have a smartphone, a pump, a CGM, and a watch which all go off in a discordant concert with one another with no clue that the other is alerting or any mechanism for stopping the noise save for turning off the device. In short, my wish is that the companies making these devices would give more care to the _design_ of the ecosystem around them, not just their individual device. I know, this is an emergent problem, but one that I've dealt with nightly at 3 AM when the devices go awry, not my diabetes, which is actually quite stable. The vast majority of my disease control and management issues arise from technology. Like insulin, it's the exogenous nature of the device that indicates there will be side effects, whether we design for them and manage them, or not. Unfortunately, patients pay with their user experience, all day, every day. There is no greater use case for the design of a killer app for the smart watch, i.e. wrist-worn information device, because I don't actually care what time it is. Rather, I'd be happy if the device actually made BG and related information the primary data currency of the device, not time. Time is actually secondary to the primacy of BG in this particular use case. I wear two watches to account for the fact that I need BG at a glance and the sensors for tracking exercise and metabolic impact. I've not seen a single device or interface that gives me what I want on one device at a glance without a byzantine UI.

Here is what I have in my watch:

Date, time, glucose graph, steps, pulse, time from last value, last glucose value, delta from previous value, current pump basal rate and units of insulin from the base.

More than enough to understand your current situation. Battery life after few years of use about three days.

The alert fatigue is _very real_; I have a dexcom and consistently see it:

- mis-calibrate (first day's readings are garbage after new sensor insert)

- UI on the app will sometimes mis-render by 10-15 minutes. On several occasions I have been watching the graph while dosing, didn't see any change whatsoever after 30/45 minutes, and gave more insulin because of that information. 5 seconds later the screen changes and displays 15 minutes of BG going steeply down as I would expect, but now I have 2x the dose in me -_-

While I'm swimming in sensor readings the actual impact on my treatment quality has been close to nil, but it does make the people around me feel better. I feel as if my ability to sense my own levels has worsened because I default to trusting the graph over how I feel.

I think you’d benefit from an app like InPen that lets you save your novolog settings and graphs the insulin remaining in your body for you. It sounds like you don’t understand the curve. It also warns you if you’re doubling doses to dangerous levels of stacking. You really need to learn not to do that no matter what the graph says. Can you get an appointment with a diabetes educator?

If my body wouldn't dislike those I would agree. But my experience is after about a day the results get so mixed up and unreliable that it's pretty much worthless. Hopefully they get better over time.
