Day 4 on the G4 (hah!) and all is still going well reading wise on the 2nd sensor. Since having to restart after my shower it has been working fine. If anyone has tips on keeping the sensor site from freaking out during a hot shower I'm all ears, as I'd rather not loose 2 hours of readings 3 or 4 times a week!
Other than that my trend of 3 - 4am lows continues. The only thing that has been waking me up is the Dex which makes me wonder, how many times have I had numbers these low overnight and slept through them.....
