If it is a hypnotic CD for sleeping, it is better to listen to it before going to bed, and fall asleep while listening. First of all, I don’t know what type of hypnotic slimming CD you are listening to, but generally speaking, if it is about losing weight, it is better to listen to it at other times, such as in the morning or afternoon. It only takes time to listen to it once. Hypnosis does not really make you fall asleep. When listening to the CD, try to let the guidance in the CD work on you to achieve the effect. Generally, certain results will be achieved within a 20-30 day cycle.
