In Cathy O'Brien's PTSD TIME TO HEAL book ~
she makes a Huge Point of the Importance of Wearing a Watch ~ excerpt:
'…consciousness equates to a concept of time which is the opposite of dissociation or "missing time" … So, wear a watch. Watch your watch… a cell phone is NOT a substitute…stay aware of time all of the time…This keeps you from Slipping into the mind/ brain RUT of Dissociation' !!!
