Is it worth it to listen to the hypnobirthing CDs without taking the class?

[Anonymous]

To any posters who have taken/are taking the hypnobirthing or hypnobabies CD -

do you think it would be worthwhile to listen to the hypnobirthing relaxation CDs
without taking the class? I'm going to take a Bradley class but thought about
listening to some relaxation CDs for pain management as well. I've been
hypnotized before and have worked on self-hypnosis as well, so I thought it might
be worth it to listen to the hypnobirthing CDs, but would welcome your comments.
