Back when I needed to go for a sleep study in a clinic, it was a bit of a pain to find one nearby. To make it easier for those after me, I decided to build an interactive sleep clinics map.
I have about 1200 now and covered pretty much all of the UK and United States. I'm half-way through the Canadian sleep labs and have Australia and Germany lines up too.
I was hoping you could spare a minute and check to see whether the clinics you visited and know of are included. Changes are I missed a few but would like for it to be as complete as possible.
The map is in the middle of the page here: http://www.cpap.co.uk - a bigger version will be available soon on clinics.cpap.co.uk but until I have all major English speaking nations, that's the place to find them.
It tries to detect your location by your computer IP address so hopefully it will zoom in on where you are pretty accurately. If not, just punch in your zip code, town name or state.
If you could please let me know any missing clinics, that'd be grand.
Thanks,
Joe
