I Have Extensive Fibromyalgia That My Neurologist Diagnosed As Advanced.

I have extensive fibromyalgia that my Neurologist diagnosed as advanced. I have been on Lyrica for years, until it felt like it wasn't working. He then added Savella to my am/pm regiment of medication. I have felt a little relief, but want to make sure my Neurologist hasn't over-prescribed my Lyrica. I am on a lot of medications, at very high doses, and try to keep up with each increase as I am trying to do with the new level of Lyrica recently prescripted. Thank you for any advice you can give me on the maximum dose of Lyrica a patient should have in their system. I also thank you for your time in reading and responding to my email.
