I tried the Dexcom free trial and found it interesting. I don't think I really need it but found it useful to look at directions bs was moving in. It reinforced what I believed the effect of certain foods would be but surprised me about the delayed effect of exercise. It consistently read differently from my blood meter.
My reaction to it was interesting too. Whereas I think I am well controlled after 32 years with type 2 I found myself getting a bit paranoid about number checking. It wasn't good for me mentally.
Overall I was glad I'd had the chance to try one. Good luck.
I found it interesting. The results surprised me. The biggest spike in 3 days of using it, Kellogs Bran Flakes was the worst. It went up to 10.1. As a contrast, i had 7 bottles of Efes pilsner. I didn't go over 8.5, so was very surprised. I tried to get it to spike higher, but i gave up. From Greggs sausage rolls, rye bread with a small scrape of jam, noodles and basmati rice, nothing except the cereal has spiked over 10. I suppose, as it is bran, which i got to try to get more fiber, they have put lots of sugar in it.
