I am sure this will
"I am sure this will be a 5 star for other users but, I am suffering with terrible cluster headaches at the moment and understand there is no tablets etc. to help other than oxygen. In general, they say use oxygen to break the cycle and that might get rid of the cluster headaches. So, my wife bought your product hoping it will break the cycle but so far although it has dulled the pain, it has failed to break the cycle and I have terrible attacks. But it is a good product, and I am sure has helped others."
