If so, can you please let me know about your experiences of it and if you found it worthwhile. I have received a fairly hefty manual which is designed to help you understand and practice the technique at a beginner's level but I think it's fair to say I am viewing it with a healthy dose of scepticism at the moment. Before I dive in and plough through the manual
, it would be helpful to know the thoughts of those who have experienced it.Thanks!
