Well everyone certainly has the ability to go into the alpha state and there may be some success in hypotherapy even in this state. It is quite easy to tell what sort of level of success you will have, because you can practise relaxing at home. If you can reach a state where there is little thought going through your mind, and you are just totally there in the now, and you can hold this for a large length of time (this is my biggest problem), then you will get the greatest benefits from hypnotherapy. If you have trouble reaching this state, then you might be wasting your time and money in hypnotherapy.
