I've been doing this diabetes thing myself for about 1.5 years now. I've lived with my mom's own brittle T1 diabetes for the 22.5 years that preceeded my own diagnosis. I know all about fluctuating sugars and the benefits of knowing where you're at. Even so, there are a host of reasons that I'm not stressing my lack of CGM right now, nor am I too worried about jumping on the bandwagon in the near future.
1. I'm (generally) predictably in control - I'm getting pretty good at dancing the dance and being able to gauge the outcome. Maybe that's a factor of my age, my diet, my own continued insulin production, or luck. I don't know, but it's working well for me now, so I'm gonna go with it.
2. The variability of accuracy worries me - I hear stories. Sometimes they are spot on, sometimes they are 200 points off. I understand that they are going to have accuracy issues, just like conventional meters do, but those issues would aggravate me, and I see no reason to add such aggravation to my daily routine right now.
3. I'm not having babies anytime soon - I don't need to be in such religiously tight control for procreation purposes.
4. I don't want to deal with alarms, especially if they are potentially incorrect or about lost sensors.
5. I don't have any problems with hypo unawareness or not waking up when I'm low.
6. I don't want to give my diabetes any bigger a stake in my life right now - I think this is the main reason I don't want to sign up for a CGM. There's a certain danger for obsession that I think would come with my having access to my BG numbers every five minutes. That's just how I am. Though a CGM would certainly keep me more informed about what my BG is doing and maybe even why it's doing that, I do not want to give diabetes the invitation to dominate my thoughts right now. Control can go either way, and I'd like to remain the one in power.
I can't stress this enough, THIS IS AN ENTIRELY PERSONAL DECISION AND RATIONALIZATION BASED ON MY OWN EXPERIENCE. I'm sure I'll change my tune in a few years. I'm sure I'll eat my words eventually, but for right now, I'm happy to step to the back of the line and let Blue Cross pay for everyone who is ready for the technology.
