Seeking fitbit data for a book project

I am an editor at O’Reilly working on a book about how personal health
data can be stored and manipulated in Microsoft’s HealthVault. The
author would like to show how to upload sleep data from Fitbit and
manipulate it, and asked whether I can get a few months’ worth of
sleep data from someone saving it to Fitbit. Would anybody be willing
to send a file? We’ll thank you in the preface (unless of course you
want to remain anonymous!). You can respond to me off-list.
