So, I now have to wear a continuous glucose monitor (CGM). I must admit, I'm surprised. I have a big issue with needles and was afraid of putting this thing on my arm every 2 weeks. (Freestyle Libra 2) While I did need a little experienced help in placement the first time... I didn't feel anything. There was the pressure of something pressing against my arm, obviously, but nothing beyond that. Honestly, I can't even feel it right now. Technology has come a long way and I'm severely grateful there's an option to stabbing a finger 3+ times a day, cause that wasn't going to happen. Just can't. The instructions could definitely be clearer, even with the pics. The app tells you how to put it on, but nothing really says that you have to scan the sensor with the app to GET those instructions, and it implies you scan after you put it on your arm. Kind of a stupid loop there. Once you're on and in the app, though, it's nicely explanatory and even shows how many days until it's time to change the sensor. We'll see how well this works. I'm just mainly concerned about sleeping. I put it on the side I don't sleep on, but you're also supposed to switch sides each time. I just don't normally or comfortably sleep on the other side or my back. Sigh. Now I'm just waiting for the covering patches to arrive today that I ordered. Those will be reviewed separately. Stay tuned!
