By the time I was referred to a neurologist, at least a year into therapy, my meds had changed to 250mg Lamictal, 15mg Abilify, Topomax, 2400mg Neurontin
, 1 1/2 mg Klonopin...I had been on those since I stopped the Lithium due to side effects after 6 months. My weight came down, I had no other side effects, but my headaches were still raging after 1 1/2 yrs. of therapy. I knew it wasn't the meds, because even as I changed them, my headaches still followed.
