Have tried all sorts of stuff to counteract that - see my first post, including correct breathing, relaxation, soothing sounds, motivational techniques, anxiety
and stress management
, visualization, positive thinking, diversion tactics, occupy myself, etc. Have even changed my bed and matress, pillows, etc. Have made various lifestyle changes to try and crack it but with no positive results so far - just ruling things out such as sitting at PC, posture, diet, etc.
