I am currently taking 30 mg 2x per day for cervical neck deformity. The cymbalta definitely helps with pain but I am struggling with fatigue, sleepiness, no desire to work whereas I used to be a workaholic at a job I love. I don't laugh... saw the dr today and she suggested increasing dosage of cymbalta to 120 mg. I am hoping to get some insights on this move. Thank you in advance.
