I have just went up to 120 of Cymbalta.I don't know how long as I think everyone is different and some may be slow benefits. I had taken this before but only did 60mg which is the depresson dose. I have heard people on here state they are on 180mg. I have been told though usually 120. I just went on neurontin too but am on a very low dose still 900. My doc said at least 1500-3200 I think. Do you feel neurontin has helped? What side effects do you have? I know for me nausea came with it so I eat with it and make sure my stomach is full. I did adjust though. Sorry not much help but I hope you see more benefits asap
