My mom has been taking 30 mg of Cymbalta daily for chronic pain since Jan. 2009. She said it doesn't help and wants to stop taking it, her doctor wants her to continue using it. I'm afraid she will stop it suddenly and have withdrawal symptoms and suffer more. She had problems with other depression and anxiety meds that she abruptly stopped in the past and went thru major withdrawal. Is there a right or wrong way to wean off the drug?
