Bipolar Disorde
"I am currently on 3200 MG a day (was on 2400 a day, but after 5 years started to develop a tolerance).  I have been put on it for my bipolar then taken off of it then put back on it for an injury to my neck.  After several nightmare drug trials including Geodon, Tegretol, Lithium, Seroquel, and Zyprexa and more... I will never again stray from this medication.  The ones in the list that did help caused horrific side effects mostly being a feeling like restless leg syndrome (except with Seroquel it was all over my body), and with Lithium I have never wanted to commit suicide as strongly as I did on the two times I attempted that medication.  Neurontin makes me calmer, sometimes giggly I admit, and sometimes zoned out but this is rare."
