Are there side effects?

Usually the main side effect of hypnotherapy is that you are left feeling calmer and more relaxed! Hypnosis is safe. Hypnotherapy is simply about guiding you into a relaxing trance-like state. In fact, when you think about it you are often in a similar trance state on a daily basis. Just think of times you have been sleepy but not quite asleep yet, engrossed in focused concentration, been preoccupied daydreaming or found your mind wandering during a conversation or class. These are all examples of being in a type of trance, very similar to a hypnotherapy (hypnosis) trace state.
The difference is that you were not guided into the trance by a therapist. Hypnotherapy is safe and suitable for both adults and children.
