In the previous FAQ item, I speak of instant changes one may notice. But every one is different, both in the depth of trance state achieved with hypnosis and with the degree of change noticeable after the session. People used to meditation, mind work, or hypnosis, typically achieve swifter change. The mind can be trained, though. You just have to teach your brain to respond, and prepare yourself to relax and get out of the session as much as you can. It is an effortless process once you let your mind "go". The change could be gradual or instant, depending on the issue being tackled.
