Typical start up side effects of
Cymbalta would be an increase in anxiety (feeling
jittery), insomnia or drowsiness, GI disturbances (lack of appetite, nausea, diarrhea), headache.
Typically, start up side effects will start to improve about 2-3 weeks in.
Just give it some time. You can probably take it at night, it may help how you feel, at least during the day. Ask your doctor.
Hang in there dear!
