Sorry if this is mentioned in one of the tutorials or something, but does staying up later than usual inhibit dream recall/lucidity? I heard that stress was a major roadblock in the lucidity process, but what about this factor. For example, on weekdays i go to bed about 10:00 and wake up around 6:50 or so. On weekends, though, I might go to sleep at 11:30-12:00 or later.
