Reading about this may make you feel crazy or insane but the truth is this is a real problem people men and women are having problems with I just got a new client that is suffering from this problem. First thing I did was look up all the cemicals in the body that relate to this problem.
One thing I found is they do not drink water so one way or another there pressure may drop or rise in the blood.
Causing the body to not have enough o2 to move threw the blooding causing a server head ache.
I will be adding more soon.
