Yeah, I'm familiar with this effect, and the power of sugar tracking. However, my story played out differently so far. I've always been a hardcore night owl. Since having kids, my sleep went completely down the drain and stayed there for ~8years now. Once I started to wear my watch at night, and seeing the sleep stats, I actually felt a stronger push to force myself to bed early. So for me, it has had a positive effect.
