So far I'm liking my zeo, but I've noticed that it seems to have trouble telling when I am actually sleeping. For example, the night before last, I could not fall asleep for 3 hours after going to bed. The zeo said I was in deep and some REM sleep during that time. I thought maybe I really was sleeping, I had just not realized it so I brushed it off. Last night I woke up once at midnight for about an hour. However upon looking at the charts this morning, the zeo again says I was sleeping for much of that time. There is no way I was sleeping for that hour, as I was wide awake and left the room at one point (which helped me get back to sleep actually). I think the zeo seems to think I'm sleeping whenever I am still. If anyone has any ideas on how to get the zeo to better register when I am actually awake, I'd appreciate some suggestions.
