This module helped me to identify symptoms that I did not realize were stress related.  I have found that my breathing becomes irregular while under stress.  I rely more on caffeine when under stress.  My commute is a big stressor as well.  I watch television too late at night which reduces my sleep time adding to fatigue.  I'm a mess!  I will definitely be making some changes, like: exercizing, reducing caffeine intake, and getting to bed earlier!
