Hypnotherapy

So let's get started.  Does anyone have experience of hypnotherapy? I am about to have a few sessions to, I hope, help with dental phobia.  I am due to have some treatment and I am very worried.  I have discussed this with friends and they have said that hypnosis is likely to help. I would love you to post on my blog if you have had hypnosis, and please let me know whether it was successful or not.
