• 7. Treatment with oral morphine greater than 60 mg a day or equivalent

• 8. Other causes of fatigue, including, but not restricted to:

  1. untreated hypothyroidism

  7. uncontrolled cardiac disease or cardiovascular disorders
  8. acute infections
  9. major depressive disorder
  10. uncontrolled neurological disorders
• 9. Concomitant use of other medications/dietary supplements for fatigue
• 10. Concomitant use of cannabidiol (CBD) or Tetrahydrocannabinol (THC).
• 11. Any other invasive malignancy from which the patient has been disease-free for less than 5 years with the exception of curatively treated basal or squamous cell skin cancer
