I probably will try to explain more later, and add alt text, but for now, this is the wonders of open source diabetes automation. I've told the system my guess of the carbs I had. I added some insulin, but not nearly enough. I did some random guess of "there were fats and proteins, a bunch, pretend they're this many carbs over this period".
And that was the extent of my thinking, and interactions with it. And it kept me *well* within range.
