Don’t go into surgery without using this! It has been described by one family as a miracle! The CD is to help you prepare for and recover from surgery. It is best to listen to it daily before and after surgery. You may listen either asleep or awake – it will work fine either way. Not to be used while operating large machinery, such as a car. On the CD, Track 1 is an introduction, Track 2 Pre-Surgery and Track 3 is for Post-Surgery.
