I tried this and was up to 120. At first it made me super nauseous which my pain doc said was normal and would wear off after a few weeks which it did. I started at 30 after dinner to help with that. It is an expensive med but if your insurance does not cover ask your doc about writing the company because sometimes they will send it to your docs office for free or less if you dont have med insurance.
The thing with meds and if they help or not etc is we are all different so what may help one person may not another. I was also on the combo of neurontin and cymbalta at that time too. Though neither helped me but I did not feel it hurt me either.
I hope you find what works
