Has anyone practised and experienced Byron Katie's "The Work"?

Have you read Loving What Is written by Byron Katie? in which she explains how to do The Work

I’m coming to the end of the book and although I get the concept I’m struggling to get clarity on any thought I start with…I don’t feel better about stuff at all…I can see how it works for other people having watched lots of the clips but I’m pretty stuck…

I feel like there are so so many thoughts that I get into one and another pops up…and then another and another…the four questions just seem to lead me deeper and deeper into more and more questions…without answers…or peace

I wonder whether any Jellies have read this book or had experience of Katie’s work or other books? How long have you been doing the work for? Can you tell me your experiences please?
