Well it’s a 24/7 high wire balancing act, and not just in terms of BG levels but also in terms of psychology. The great thing about CGM systems, f’rinstance, is that they are, well, continuous: they give you a whole movie, rather than just still-shots of points along the time-line. Trend info, yay. Many of us old-timers remember when finger-stick BG meters were The Next New Thing—just think of how much better my control would have been through the 80s, 90s and Oughts if I’d had access to that timeline info instead of the occasional result scrawled in a notebook I mostly only remembered to keep up the week or so before my next appointment.
All good… but… little acknowledged CGM side-effect… you can get, well, a little obsessed with it, can’t you. And even that obsession kind of teeter-totters between good and bad. I think I notice this even more now that I have it on my wrist as well as my smartphone. Everyone knows how rude it is to look like you’re checking the time in a social situation, and I’ve felt myself violating that etiquette frequently. I’m not looking at my watch, I mean I am but I’m not checking the TIME. I’ve actually gotten to the point of explaining that nine times out of ten if I’m looking at my wrist it’s to see my BG.
Spouse: “What time is it, hon?”
Me: “Oh, sorry, dunno, I was looking at my blood sugar.”
Because I gotta eat in half an hour and do I need to pre-bolus now and how much, or I’m planning a bike ride in an hour and do I need to do a temp basal, or a million other reasons. But no one else around me lives in that mindset, and I hate inflicting it on them but…
The thing is, to have really tight control, you pretty much HAVE to be obsessive about it, and that’s a two-edged sword. I liken it to the discipline of playing an instrument at a professional or advanced-amateur level. It is necessary to the art, but art is well known for demanding more at the expense of other things of value in your life. It feels unqualifiedly virtuous even as it is distracting you or interfering with other important activities, making you seem self-absorbed or actively rude. Same with participating here. I want to share successes, techniques that have worked for me, whatever—if I can’t obsess about it here, where can I obsess about it! But how that communicates to newcomers, especially the newly dx’d, is a real consideration. I remember how utterly overwhelming it felt at the beginning, invading every aspect of my life, and here’s this whole crowd of people obsessing about stuff I never wanted and didn’t sign up for and my numbers suck!
TL;DR: Good point, @MBW
