Depression :: Duloxetine And Nightmares

I've been on duloxetine for about 18 months now (I think, my memory's awful) and have always had disturbed dreams and nightmares while I've been on it. Originally I was taking zolpidem 10 mg and Quetiapine 100mg at night but I've taken myself off of those over the last few months. The nightmares have gotten worse though, they're incredibly realistic. Last night I dreamt that I was drinking and I woke up heaving and with an intense headache like I was hungover. Then I managed to go back to sleep and after dreaming that I was back at my parents house and arguing with them, I woke up in such a state and my anxiety was so high I couldn't even move, I was struggling to breathe and scared because I was struggling to differentiate between what was real and what was a dream. I never wake up feeling rested and am constantly tired and yawning throughout the day, I've also been suffering more with headaches. Has anyone else on duloxetine had issues with sleep and dreams and is there anything that helps?
