Hi, yes HA = headache...we use many abbreviations and have a page listing most of them. here is the link-

The mucus is in part due to sinus and many with compression and overcrowding do have their sinuses affected...they are up there, just like the pituitary gland...many have that compressed too....
So, if u have compression of ur sinuses then u may have PND, and that can lead to GERD....
The anti inflammatory foods can help...keeping hydrated can help....
Y u get sick when u hydrate, not sure, mayb u r over hydrated....sorry, I have no idea.
Taste...even the smell of things has changed for me, so I understand what u r saying.... again this can be due to the sinuous issues, even GERD/reflux can affect how things taste.
But what we all have to remember is this is our control center...everything is controlled thru our brain stem and spinal cord, so if it malfunctions everything can malfunction....
Hope this helps
