Thanks for your response.
At this point though, I don�t have much to add. When the OP posted the question I assumed that the thread would take the direction of those who it worked for giving some reasons as to why it worked for them and those who it didn�t work for would give some reasons as to why it didn�t work for them.
The OP would then have been able to get a better understanding of whether it would work for him/ her or not.
