This is Dr. David
cymbalta should never be stopped cold turkey. it always needs to be tapered down gradually to stop.
I'm glad you have started back up cymbalta 30.
cymbalta and prozac together can have risks for causing SIADH syndrome of inappropriate anti-diuretic hormone
and can increase risks for serotonin syndrome.
sleep is a complicated physiology and you need a full sleep evaluation
cymbalta can cause insomnia in some patients
are you still having depression symptoms?
you may benefit from seeing a psychiatrist to help you with these medications
and a sleep specialist to help you get better sleep
regular exercise can help you sleep better.
better sleep habits can help you sleep better.
I would talk to your doctor about the potential side effects of cymbalta and prozac which I mentioned above.
let me know if you have questions.
