I read this book: HypnoBirthing: The Mongan Method: A natural approach to a safe, easier, more comfortable birthing. It comes with a Hypnobirthing CD. The book is very good. I took a private class with my husband from a hypno-therapist in Minneapolis (I don't have info with me, but if you want it let me know and I'll look for it).
I didn't use drugs during my birth. I felt that my birth was still pretty intense, not painful, but I had moments of thinking "why didn't I get drugs". I never gave up though and I feel proud of myself for going all of the way. I didn't have any complications. This was my first baby. I started my labor at 9:30a, was at the hospital at 1p and started pushing at 5:30p and delivered at 7:32p.
If I could redo it, I would do two things differently. 1) When I went into labor I tried to take care of a bunch of things for work and last minute packing, so I wasn't relaxed. I would forget everything and start practicing the hypnobirthing techniques to get into a relaxed state from the beginning. 2) My husband went to the class with me, but didn't practice with me. I think it's important to have someone at the birth that is going to be your hypnobirthing advocate, so your not on your own.
I would do it again with the two changes above.
Hope that helps,
