I am currently taking 30mg of cymbalta for nerve pain and axiety due to this pain. I have 2 herniated discs in my neck. I have had a few treatments over the last year and I feel the need to wean off of the meds. My doctor has me taking 30 then 20mg every other day. Yesterday, we decided to start using prozac. he said when i start taking 20mg prozac, I should cease the cymbalta due to the low dosage. I wanted to see if this was a good method. I am having minor withdrawals from the current 30/20 method such as irritability and brain fog.
