I've been on all the SSRI's. For me they work great for awhile then they stop working. I have a low tolerance for meds. I am currently on Cymbalta and like it a lot. I had to go off of it for about a week and didn't like that at all so it proves to me that I still need the med. With that said everyone reacts to meds differently. I hope the best for you and mention it to your doc about your symptoms maybe a med change is due.
