Re: [IP] Minimed CGMS Realtime or DexCom

Thanks, Nikos, for the additional information.  The two horizontal lines
you describe are similar to the Dexcom in that regard - they show the
high and low threshholds you've set.

Apparently that is true for many Dexcom users as well - I gather that
some people are getting good data right from the start.  (Rick, others?
What has your experience been in this regard?)  Unfortunately, it hasn't
been true for me.  I just wanted to be clear that I'm not speaking for
all users of the Dexcom here.

Same for the Dexcom.  I've had some cases where the sensor is giving bad
data (like only a few hours after insertion) where restarting it and
recalibrating fixes the problem.  So it sounds like the devices are
pretty similar in this regard.

As a side note on the psychological change from wearing one of these, I
find myself getting annoyed when I have to restart and then I won't know
my BGs for *two whole hours*!  :-)  I have to remind myself that it
wasn't very long ago when I usually didn't know my BGs for that amount
of time.
