depression
"Have been taking 300mg for 3 weeks now.  I had HORRIBLE side effects in the beginning (for about a week) - almost unbearable nausea, diarrhea, sweating, vertigo, headaches, confusion and I felt like I had the flu.  Now I have migraine headaches that last almost all day and ringing in my ears.  I still feel a little foggy sometimes but that is a small price to pay for my depression being pretty much completely gone.  I finally have energy and I am shocked at how quickly it worked.  I was suicidal for months while on 225mg of Effexor and this has been a life saver."
