anxiety
"I took Cymbalta for 7 weeks for post-partum anxiety/depression. After the initial week of feeling nausea and fatigue, I started to feel better. I stayed on 30 mg, but found after 5 weeks I was having vivid, disturbing dreams, insomnia, sweating, and the anxiety came back. 

I started tapering off, and even at the low dose the withdrawls are quite uncomfortable - after tapering and stopping the drug I still get a buzz/pulse/shock like sensation in my head almost constantly after a week. Great if it helps, but hard to get off!"
