Why does Cymbalta make me so tired?

I was just recently increased from 60 to 90 mg a day. I've been on it for about 6 yes now and it never made me sleepy. I always had energy with it, lost a lot of weight and the increased dosage is helping tremendously with my fibromyalgia and depression. I did read that the tiredness is a side effect for some.

Are you still on cymbalta? I have tried everything too and cymbalta works wonders for me, however I can't function on it. I have severe chronic fatigue and can hardly get out of bed most days. Have you tried anything else with it and had any success? I am currently trying edronax!!

cymbalta done the same for me too but it also caused insomnia

Hi Sphynxxx! I don't know what mg you're on, but I was on 30, and it did the same thing to me. They switched me to 20 mg, and I take before bed and this seemed to resolve it. Hope this may help. Take care, Trkey

Unfortunately, this is a side effect for some people. I was on Cymbalta many years and endured this issue, but eventually asked to be changed to another antidepressant because I was sleeping too much.
