Hypnosis works really, really well with anything anxiety based. It may be one of the best treatments for depression. It is also really effective with memory recall for law enforcement, but you have to be careful not to implant false memories and not lead the subject. Pain management for chronic pain so people can get off drugs works really well also. And of course, smoking cessation and weight loss are any hypnotists bread and butter. I do clinical work and get a lot of my clients from Healthcare referrals, so I try to stay away from any of the metaphysical stuff.
