You definitely went through Cymbalta withdrawals. I was on 120mgs of Cymbalta, it was working great, my liver enzymes went sky high and I had to quit the Cymbalta cold turkey. That was the worst week. I had the chills with no fever, body shakes and aches, violently ill, couldn't eat, my mood tanked. The only good thing was I was in the hospital already. I am now on Effexor XR and have heard stories about coming off of it.
