Okay, a book.............
So I went snorkeling/swimming today for 2 1/2 hours, really nice water temps and the sun was out. Lots of turtles too. And maybe a barracuda, but it swam away fast so I'm not sure. We see one at another swimming spot all the time so I do know what they look like. I had to calibrate my Dexcom because it was 26 points too high, my Libre was 18 low before we left. I get there and my Libre says 4.2, but my Dex says 7.2. Pull out my meter to test because the Dex was off so much earlier and even though I calibrated the sensor is on it's 28th day so it could be going, and my meter battery is low. Okay fine, my number is probably in between the two and that's fine, I'll watch for a drop. I had reduced my basal rate and didn't eat except for 10 carbs to boost my Bg level to be able to swim. I should be good.
I went out past the point and a really strong current was out there so a lot of work and I did that twice, I was staying great and my Libre ends up quitting, the battery says low, probably the button got squished on while stashed in my swimsuit in it's pouch. But I feel fine, I had been stable for the first hour and a half which is when I am more prone to drop and then I start to climb at some point. When I do get out and in shallow water I get a Dexcom reading...........9.7............walk to the car 11.9, take off my equipment and dry off 13. Took 10 units because experience has told me it's always a stubborn high. But no Libre, no meter and a Dexcom that might be wacky so......
I start to come down, staying fairly stable, great! I dose to eat and 8 hours later I am nibbling odds and ends because I keep dropping. I keep thinking I've eaten enough to stabilize but I guess I needed to reduce my basal hours ago (hindsight) but I will be doing so for bedtime tonight.
Okay swimming with turtles is worth putting up with the highs and then lows, but it is one of the most annoying things to have to eat to exercise, to have higher numbers than I ever do in a "normal" day and then eat when I'm not hungry. Exercise is supposed to be good for you lol, but what we have to do sometimes to be able too?
But overall a beautiful day, some good turtle video and a nice workout! Battery's changed in my purse meter, The Libre's charging and I will leave on the Dexcom for the night and change it out tomorrow because it was off and reading high again.
