No. The results you can achieve with self-hypnosis are limited, because once you enter a deeper state of hypnosis, it's as if your conscious mind is dormant, and you're unable to consciously give yourself hypnotic suggestions to make the changes you desire. Without proper self-hypnosis training, you may inadvertently reinforce negative thoughts, emotions, behaviors and habits instead of making the changes you want. In other words, if you don't know what you're doing, you could end up feeling worse instead of better. Your hypnotist/hypnotherapist can teach you effective self-hypnosis strategies.
