I just left a comment on another thread about recommendations for courses. I definitely would attend a course as the exercises are demonstrated ensuring that you'll leave the course knowing exactly what to do and when to use them. I've signed up with an awesome teacher named Reshma. You can find her on
www.hypnoclinic.net. She works in the same clinic as Helianthe that is mentioned in this thread and taught with her. My sister had a brilliant experience after attending Reshma's course so I cannot recommend her enough. There are lots of positive comments on different forums about her. She taught in Wandsworth before from the Vitality centre and now teaches from somewhere in Wimbledon. There are options for courses so check it out!
