Depression
"I have major depressive disorder. I have suffered very low energy since I was 12 due to depression. Sleeping or laying in bed for 16 hours was normal for me. I was on 200mg each morning in combination with anti-depressants and a sleeping pill at night. I noticed no side effects from modafinil. I am no longer on this medication because it did not help with my depression, just helped with a symptom of my depression. (low energy). I was put on an MAIO anti-depressant and therefore could not continue with this medication due to interactions. But it did give me energy."
