Yes I do just live off of the Dex especially if the sensor has "aged" properly and been on for at least 4-5 days. Then I get great readings that are no more than a few points off the glucometer so I don't see the point in doing both plus it is a lot easier on my fingers. So I do the required 2 calibration tests a day and leave it at that. I don't think my doctor would be all that surprised and Dexcom expects you to only do 2 blood glucose readings in a day so I doubt either one would have a problem with it.
Dexcom says that you are not supposed to make any insulin dose decisions without first doing a finger stick. I say, GET REAL! After you've been using the G4 for awhile, you may be able to judge whether its' reading is accurate or not by how you feel & what you've been doing that day for food & exercise. Sometimes you'll judge well and occasionally you'll screw up, but your fingers may get some rest and I'll bet that you won't suffer any long-term damage. I'm glad to hear that you are giving yourself a little breathing room. Happy G4 Day!
Here's what my wife recommends using for those finger cracks: http://www.vermontbeebalm.com/
she believes that the 'original' bee balm is best.
I use a Freestyle lite meter and I was initially forced to use it against my will by the insurance company that no longer allowed One Touch strips. So as much as I resented being forced to use this meter, I have to say it uses a tiny amount of blood and from the 5 that they sent me I have chosen 1 which generally matches with how I feel and is very close to what they get in the lab so I am pretty happy with it. But I'd still prefer not to have to do it at all and the Dexcom almost allows that.
I had 3 freestyle lite meters that had been sent to me and one morning I got up and felt perfectly fine so I did my bg and the meter said 62 ? So I said, that is not right, so I checked with the next one and it said 80, so then I decided make it a trifecta and tried the third meter it said 76. That they can be that far apart and still be considered "accurate" as far as the FDA is concerned really pisses me off. I called Abbott and complained and a couple of days later I got 2 more meters and 100 free strips. So now I have 5 freestyle lite meters, 2 Insulinx meters (which use the same strips)and a prescription for 12 strips per day from my endo. I don't use them much anymore the Dexcom system has really changed my habits. I too was diagnosed many years before home BG testing, we had clinitest urine testing tablet kits, oh so much fun. But I agree the technology has not gotten significantly better in the last 20 years. Much as I hate to say this, sometimes I wish Bill Gates' kid had been diagnosed with T1 because by now we would have an I-Pod that not only played great music but also functioned as a CGM and pump. But I understand how awful a thing that is to say.
I hate to say I bolus from the G4 but if the readings aren't in extremes (50's or 200's) I'll go ahead. At least after day 3 I will. So far it's been damned spot on to every finger test. I did stop doing multiple stick tests to check it though. As someone said to me "a man with a watch knows what time it is. A man with 2 watches is never quite sure".
You can look back to where you started the sensor, if you push the button and go to settings, and device info, it will tell you exactly when you last started the sensor and also the last time you calibrated as well. If you restart the sensor then it will tell you the last time you restarted it.
