I just found Quantified Self. Looks fantastic.
I have been tracking some things (like HR during workouts, and various other data of the workout) forever. And I have done blood glucose measurements on and off with the old finger-pricking method. (I had gestational diabetes during my pregnancy--so I had all the stuff from that. And it means I'm at higher risk of diabetes. So it seems worth watching every so often.)
I very recently started using a CGM, and I have been thinking about ways to link all the things I want to link. Which is everything. heh.
Sleep, mood, food, exercise, blood sugar, energy... all of those
This looks like a great forum.
