thank you so much for the reply.

great help.

im still in 2 minds..so many pros and cons(to call it that) of each, at the end of the day no matter how much conflicting advise people give me i must make the decision at the end of the day ...which is what im finding hardest!

thank you very much and i hope your succeeding in managing peoples pain!..my mum would be a great candidate of yours..typical chronic back pain followed by depression and all that goes with it. we all do what we can tho ey. x
