Hey Cindy!
Yes, this will pass. I have been taking Cymbalta for a long while now and had this same reaction. It does tend to make u jittery and sleepless for awhile at first and will upset ur stomach too at first. I thought it was maybe my GERD in combination with the med, so i was taking my GERD med with the Cymbalta med at night, but come to find out it was not. I am not taking the GERD med in the morn as I normally would and the Cymbalta at night (due to sleepy effect!!!) and am doing just great!! Hang in there and give it some more time. It should work out soon.
