I've just got my first cgm. It started working an hour ago and my BG was 48, and dropping. I ate a 25g candy bar and have spent the last hour delightedly watching it climb - 88 and counting (it's leveled off now, so I'm going to have my normal dinner and shot). This is amazing; I've been Type 1 for 35 years and have no awareness of low blood sugars - often find myself collapsing out of the blue and discover I'm 20 or lower. The one challenge is going be the fact that I live in a Zen temple and spend 90 minutes every morning meditating in a perfectly silent room with 50 other silent people. I take a morning shot of Humalog to deal with the Dawn Phenomenon, and am often low by the time we're done meditating. But I'm determined to make this work; I think it's a life-changing piece of technology.

Wait till you d/l a week's data - so much info!

Totally agree with Richard. I tend to almost ignore the first day. The sensor has to kind of 'marinate' - I actually find the second week even more accurate than the first.

Remember that the readings from the Dexcom are from interstitial fluid, not blood, so are not always accurate. It's a fabulous tool for seeing trends, but not for dosing.

Enjoy! Gassho.

Its amazing for knowledge! But....do not trust the numbers. Cant tell you how often I trusted the dex, treated a low or bolused for a high, only to figure later that it was wrong and messed up my day! Just remember to test before treating lows or highs!

The alarms can get annoying too, especially when meditating.....but another thing you will work through over time.

jaya guru devi!

Anyone notice any differences in the adhesive lately on your Dexcom? I can have it peeling off in one day - when did it turn so bad? I sure wish they'd use the stuff the pump uses! That stuff is tough!

Djinn, welcome aboard the Dexcom train.... whooo whooo! :) It's am amazing product but I tend to think that people put too many eggs in one basket and not enough in another.... Let me explain.

The Dexcom is not a BG meter, I know I know that sounds crazy but it's not. It is actually taking a super intelligent guess at your BG based on how much your BG is going up or down and what you tell it from your "regular" meter. When you get into the guts of what the Dexcom actually does it is mind blowing that they are able to give you a BG number at all. So one really good thing to do, as people are saying, to get used to the Dexcom is to completely ignore the BG number and focus on what the Dexcom is really giving you which is trending data.

Watch your graph and arrows instead of the numbers because %99.9 of the time the direction of change and the rate of change will be amazingly acurate because that is what it is actually physically measuring from your body, the rate and ammount of change in your BG levels, not an actual BG number.

Some people seem to find that this it is a weakness that they can't totally rely on the BG number or it wasn't what they were expecting, but take it from me, knowing in what direction your BG is going and how fast it's going there brings a whole new set of information to the party to help you manage yourself more cloesly. And enjoy it, it is an amazing tool in your aresnal.

great explanation! Thanks for putting it into words for all of us..

Thank you for this - it's a really helpful perspective. I've always tested about 10 times day - scarred fingertips testify to that - so I'm finding that if I keep doing that and input the data into the Dexcom, it's making a more precise guess at my BG.
