I have MM too, and just got the CGM about a month ago, and I LOVE it! Is your endo able to have a trainer come in? If they can, I would really recommend it. But I'll try to answer your questions.
Yes, there's an insertion device. And I'm just going to warn you--the sensor needle is big. Scary big. But it hasn't really hurt so far (no more than an infusion set does). It looks worse than it is. I psyched myself out the first time, but it gets easier and easier each time. And the needle comes out, like a set. My trainer said to put the sensor in my stomach or upper butt, but I've been to chicken to try my butt.
The best advice I can give you is to BE PATIENT. It's not going to work perfectly all the time, and there's most definitely a learning curve. I just now feel like I've got a good handle on it. There's a lot to remember as far as calibrating and what not, so be patient with yourself. I've screwed up a decent bit myself.
Also, all the information can be overwhelming. The CGM (when functioning properly) is about 20 minutes behind what your bs is, so I'm still sticking all the time. But it's been super-helpful in identifying patterns and helping my endo tweak my basals.
Sorry for the long-winded response! Overall, I'm happy I got the CGM (though I do tend to curse profusely at it when it's not working properly). Good luck, and let me know if you have more questions.
Thank you for the info!
I should have my box of supplies tomorrow and my doctor is calling me back tomorrow to make an appointment. I had a trainer come in for the pump and it was really helpful so I will definitely ask for a trainer for the sensor.
I'm really excited to start! but i'm getting nervous about having something else on me. I hate having infusion sets on my stomach I usually use my sides, so I'm a little nervous about the sensor. Is it the same size as an infusion set? Overall though I'm looking forward to finally knocking down my high blood sugars! lol I think i'll end up just starring at my pump with all the numbers and the graph haha.
You said that the CGM might not always function properly... how often does it not work?
