There are those times when it is just not possible to really say how you feel.  There is nothing really wrong that you can describe, but you have this feeling of being lethargic and lacking any real energy.  Your body is tired and yet you are enjoying plenty of sleep.  It is time to go deep inside with an ultimate cleanse.  Your body system may be suffering from the effects of a huge amount of literal sludge that has clogged your colon.  Allow your body the freedom of rejuvenation by cleaning out all of the build up and enjoy feeling much better.
