atigue
"A brutal accident left me in a drug induced coma and on a respirator with a month long hospital stay. Figured I was back to relative normality. Fatigue was an issue, as was memory loss, attention span and nightmares. Diagnosed with PTSD, but I knew it wasn't.  

After 22 months of hell I was circling the drain and either got help or was "opting out". Checked in to a nero ward and they ran a battery of tests on meover 2 weeks.  > Undiagnosed concussion from the accident.  

Gave me an SSRI (off now) but nothing fixed the fatigue, or constant feeling of hangover/lack of focus.

Gave me modafinil and although I had small headaches daily (gone now) the energy/clarity it gave me was unreal.  Short/med memory is still shot but I have my life back"
