onetrack - I totally agree with you but I hardly ever indulge in carbonated drinks...a can every couple of weeks is probably all I ever have so I think the cause lies elswhere...
jetset lady - I fully empathise with you and in a selfish way feel quite lucky that although I have the symptoms in my limbs on a near full-time basis, for the last decade or so I have had minimal problems with my sleep...I have however heard that it gets worse with age so I hope its not a sign of things to come...
still would be interseted to read the views of any experts
