chronic fatigue syndrome
"I suffer from SAD and dealing with people and students (yes, I understand the irony of the career choice) on a daily basis leaves me burned out most days from the stress of teaching to 300 students and dealing with people, in general, but a simple combination of Xanax (0.25 mg) before a class and daily Nuvigil (75 mg) completely erased the problem.  I work all day, I'm calm and focused in classes, and with a Xanax (0.5mg) before bed I sleep a full night without problems."
