What if someone else can hear my CD?

Ask that person if s/he wants to change with you and share a copy of the script (provided with every CD).

If s/he does not want to hear the CD, you can use earphones (which are often uncomfortable) or a pillow speaker -- an ear sized speaker that plugs into the earphone outlet on your machine and fits into or under your pillow case. They are available in many electronic shops.

Is SuperSleep® like hypnosis?

In a general sense, yes. The difference in effectiveness depends on (1) the brainwave state you are in when you hear the suggestions, and (2) the quality of the hypnotic suggestions. SuperSleep® assures you are in the theta brainwave state or lower (see Research).
