                        I often suffer from fatigue too and recently discovered it was due to being in chronic pain.  Not severe pain, but enough that my body was constantly in "stress" mode.  I alleviated much of the pain by switching to an ergonomic chair and my constant tiredness has diminished considerably.  I hope this helps in some way.
