This site is providing information about hypnosis! Hypnosis is an alternative medicine that can used for a wide range of issues, categorized under Illness (Mild Depression, Pain Management, Teeth Grinding); Daily Issues (Insomnia, Weight Loss, Phobia, Anxiety, Anger Management); Break Habits (Stop Smoking, Nail Biting, Quit Alcohol); Improve Performance (Sports management, Focus, Improve Concentration, Improve Memory). It is effective as can be seen here: "In 1970, a research conducted by Alfred Barrios found that hypnotherapy had a massive 93% success rate after only 6 sessions compared to only a 72% success rate with behavioral therapy (after 22 sessions on average), and only 38% success rate with psychotherapy (after an average of 600 sessions)."
Well, that depends on how you define hypnosis. If you think along the line of our consciousnesss level, then hypnosis could be forever.
Hypnosis can occur at Alpha, Theta or Delta level. When a person falls into coma, he most probably entered into Theta or Delta level. He could still hear if you speak to him.
If you define hypnosis as a therapeutic approach, then it cannot be forever. Even if you were to fall asleep during hypnosis, you will still wake up again.
