Hi Patten, In Sept. 2006, I Was Diagnosed With Tn...at First The Neurologist Put Me On "lyrica" It Does Work...however, It Is Expensive...with Insurance It Was Costing Me $40 A Pop...so I Asked The Phamacist If There Was A Generic I Could Take...he Suggested A Neurontin "gababentin" 600mg 3 Times A Day, I Try To Only Take Them 2 Times A Day...for 1 Months Supply It Is Only $10...they Do Calm The Nerve In My Face But The One Bad Side Effect Is Weight Gain...i've Gained Approximately 25lbs Since I Started Taking This Neurontin...i've Been Taking Them For Approximately 1 1/2 Years...i'm Going Back To A New Neurologist In May 2008 To See If There Is Something Else I Can Take...hate The Weight Gain...it's Crazy, Because I'm Not Eating Any Differently, You Just Gain Weight...i've Tried To Wein Myself Off The Neurontins However, When I Do The Pain Comes Back So I Just Keep Taking Them....caught Between A Rock And A Hard Space...i Hope This Helps...let Me Know
