@Helmut. Yep! I have the Dexcom on my left arm and right now the Libra on the inside of my right arm. I think I will move the next Libra to my love handles as some people have said they have had great success with them there. I would like to save my arms for the Dexcom.
Even though the Libra2 is supposed to be more accurate with this new one, it is still 20-25 points below my blood glucose meter test while the Dexcom is within 5 points. So there is no question I want to keep my Dexcom. For my purposes I just need an idea of what my BG levels are doing with the Libre.
Right now we are snorkeling twice a week, the water is warm and Northshore is calm in the summer. And while we can snorkel all year round here, in the winter the water is a little colder, it’s almost always the Southshore only and I doubt I would care as much staying out longer on the Southshore snorkel areas. They are smaller areas. I do use the snorkeling to just swim too, just longer laps than a pool.
I have been able to safely snorkel for an hour and once I came back into shore to get a reading and went back out so I stayed a total of two hours, but by the time you go in in a couple of areas you have a tendency to just go in for the day. And a couple of times I have come out at 75-90 BG levels.
So I might skip wearing it part of the year. It’s just you can’t always know how much work the swimming will be. I am not dropping as much now, I actually have my BG level staying even keel more or it has increased on me sometimes. But you can’t predict what it will always do and I’m out in the ocean, a ways from land a distance sometimes and no lifeguards at half the areas. So I look at the cost of it as being a safety issue and right now the same cost as if I belonged to a gym.
That would be the other solve is just go in at a really high number. I have done that too, but it goes against the grain to do that twice every week. That is a choice to make too. It was just so liberating to be able to know while I’m out there what my levels are doing!
My next attempt might be to wrap the Dexcom receiver in the pouch with Saran Wrap lol on top of the sensor so it stays right on top and see if I can get a reading. I will look weird but if it works!!! And if it works I can get creative with a wrap. I only managed once so far to get a reading with it while out swimming. It’s that wanting to download all the data while it can communicate in very limited windows that’s fouling it up. You can see little lines try to form sometimes when trying.
