"please don&#039;t take this medication. i have anxiety and fibromyalgia and i am prescribed 800 mg three times a day. due to circumstances beyond my control, i ran out of neurontin 5 days ago. the withdrawal has been terrible. i know, neurontin &quot;doesn&#039;t cause withdrawal symptoms&quot; but it does, and i&#039;ve read all over the internet that i am not alone. i have quit opiate pain killers cold turkey and over came a severe cocaine addiction in my youth, these things are child&#039;s play compared to not having neurontin. i was sweating, shivering, constipated, and the anxiety made me consider checking into a psych ward and asking them to throw away the key, i cried for hours, i can&#039;t express how horrific it was and i read it can last a year!"
