I take 1800 mg (TID) of gabapentin, which has successfully controlled my Trigeminal Neuralgia for 2 years. BUT, I am starting to feel the pain sensation again, and would like to know how to increase the dose. Do I just at one more pill at a time, to the point where the pain stops, or must the dosage be increase proportionally at all 3 times of the day I take the Med?
