Well I have now been to the Drs, and am pleased to say I left a happy bunny!
Without even much of a word from me except to confirm that yes my existing kit is all signing all dancing, the nurse switched everything back!!!!!
She advised that the switch is not for everyone and not everyone should switch but its easier to transfer everyone over and then move some of us back if its not suitable. For me she advised it wasn't really suitable.
Got to say i had my case for argument all ready and prepared in my head, but am pleased that I didn't have to use any of it (pleased as i like the nurse) and had a no problems experience today!
Hope this helps anyone who experiences the same problem
