Could Cymbalta be causing the problems I've had since starting 10 months ago? I have nausea, vomiting, anxiety, sweating and just feel unwell. It did not improve the pain associated with fibromyalgia and I hesitated to start it but dr. insisted. I wanted to go off it after the first 2 months but dr said he couldn't wean me. Now I learn there can be severe reactions to quitting and I feel those effects now if I am late with a dose. It's horrible. What can I do?
