I've only been on Cymbalta for 3 weeks and I have developed really bad acne and I've never had a pimple - except for the occasional zit here and there. I am also sleepy all the time. My doctor said in order to give me my percocet prescription, I had to take Cymbalta with it, but I don't want to! Am I going to have to endure withdrawal after just 3 weeks of taking this stuff? Should I just tell the doctor I'm taking it to be able to get my pain meds - which I take for a legit chronic pain on-going issue. Any suggestions, thoughts? I would really appreciate it.
