"Awake Time" changed dramatically overnight

[pattenhere]

It's been bugging me for a while that my fitbit flex tells me that I, on average, have about 2.5 - 3 hours of restless sleep every night - even when I don't drink alcohol at all for extended periods (up to 3 months) and eat well and exercise. Keep in mind I only put my fitbit on as I'm turning off the lights to sleep - not wearing it all day. So I started going through my history and I noticed that prior to April 26, 2015 (yes, 2015) I was only restless about 15-20 min every night. I can't find any firmware updates that happened at that time and there's no corresponding major life event for me (of which I'm aware). So, literally overnight, my sleep has seem to gone down the drain. Looking forward to people's insights here and thanks in advance for your contributions.

I found that when I changed my sleep tracking settings from "normal" to "sensitive" it dramatically changed what it said my sleep was like.  Possibly check the settings and see if it's set to sensitive tracking.

It apparently was a changing of the setting to "Sensitive" from "Normal" that was the culprit. Thank you!
