4 months late but my clinical supervisor had training in hypnotherapy, though she said she didn't get to practice it as often as she'd have liked. It can be a useful tool! Like any tool, you'll need more than one to build a house. The most important thing about hypnosis is the will to believe. You gotta be willing to cede control and let things happen in order to fully participate. Your readiness in that aspect will likely help determine results.
