I was put on Cymbalta 60mg 2 days ago. For my depression and anxiety. I started taking it 2 nights ago, and I'm having nausea, dizziness and flushing. I'm on a pain contract for a work injury in 2012. I take Neurontin 300mg tid, flexmed 7.5mg ,norco 10/325, q -6 hrs prn as needed for pain. I also take HCtz 25 mg q am. propanalol 80 mg q pm. Is the Cymbalta and the meds I'm taking? Also will the yeaky feeling going to subside or should I take in the am so that the yeaky feeling be at night?
