Jan1, 2021 - The tones used to help relieve pain also produce a drowsy state, so be selective when you use this, especially in the beginning to see how you react to the music and sounds.  Some users are reporting it to be a better sleep enhancer than any of our other sleep productions.  For that reason we have looped a 1 hour long production so you can use it for napping or for sleeping.  Also, we have had reports from some users that it produces arousal, so don't be alarmed if this is part of your experience.  There is no subliminal light or verbal sounds included in this production.
