I recently switched from Lexapro to Cymbalta, because Lexapro wasn't cutting it anymore for my depression - which was getting out of control - and because Cymbalta is FDA approved for fibromyalgia and neuropathic pain. I've been on it for about 4 weeks. Every night around 8:30pm, I get really cold. I'm talking chills and goosebumps cold. No fever, I've checked. I'll wear flannel jammies, socks, and cover with a fleece blanket from neck to toes and still have goosebumps. It lasts anywhere from 2 to 4 hours. I am not 100% certain because my memory is not at all reliable, but I am pretty sure it started with the Cymbalta. Anyone else have this experience? If so, does it eventually go away? I don't see my GP again until the 9th.
