Hi, my doctor put me on Cymbalta 30mg for PTSD and depression. Everything was fine until the 4th day, I got a horrible headache that last for 5 hours and my eyes are dilated. That was last night, it is now the next day and my eyes are still dilated and I have a slight headache. I have never taking anything that made me feel like this. I don't want to take this anymore. Should I go to the ER, I called then but they would not tell me anything over the phone.
