I have been sertraline for 1 and half months and it is doing absolutlely nothing for me at all so the doctor has prescribed me propranolol and citalopram 20mg. I have to withdraw from the sertraline before I can take the other medication. But I would like to get onto the new medication as soon as possible and was wondering if anyone thought it would be ok to just go cold turkey? Would there be any withdrawl effects?
