I only had a few sessions with a psychologist, but hypnosis was very very relaxing and the effect stayed with me for a day or so toward the end. I would do it again, but at the time I was looking more for talk therapy, so I found a psychoanalyst and now that's what I do.

It was progressive. The more we did it, the longer the relaxed state lasted. I try to do some on my own, but I can't achieve the same deep level of relaxation.

Good luck if you decide to try it!
