A couple sleep observations...first, I'm wondering how long you've owned yours? It took me several weeks before I felt comfortable sleeping with it. Daily wear took about a week, sleeping a lot longer (I'm a light sleeper too). Second, I still notice that every few weeks, I'll suddenly grow really sensitive to the Band for a night or two while sleeping. Seems to correlate very closely with how tight I've worn it over the last day or so -- the tighter I wear it, the more I notice it at night.
I suppose the goal is to find the sweet spot between tight and loose, so it isn't dangling like a chandelier at night, or causing your hand to turn blue. :smile:
