Hi Carol and welcome to A2K!
It's nice to have you here.

I have been taking Cymbalta for at least 6 months and I know that insomnia is one of the possible initial side effects of this medication but it usually goes away over time. That time, depends on each individual, of course. Unless you have been instructed by your doctor to take the Cymbalta at night, I would suggest taking it in the morning and see if that makes any difference. Overall I have been very pleased with the results of Cymbalta for my own particular condition.
How long have you been taking the Cymbalta and are you taking any other meds with it?
I hope this has helped in some way and if you have any other questions at all, please do not hesitate to let me know!
