I am taking two 300 mg Gabapentin four times a day as treatment for trigeminal neuralgia. I ve been taking this for approximately five years, initially smaller dosage, of course. I ve been experiencing difficulty in walking a straight line, have stumbled a lot, drop and/or spill something every day. My neurologist has not been helpful saying I apparently I have a choice between between the side effects of the medicine or having pain. Can you help me? Sorry, did not realize there was a charge. I am not interested.
