Hello! I ve been on neurontin 100mg 2x day for about four weeks. I have mild asthma (use ventolin when needed). I would use it once in a blue moon but now have to use it several times a day. I now get these coughing fits. I also get very mild headaches now...not a headache person. The neurontin is for trigeminal neuralgia. My right jaw has been hitting for twenty-five years. I even had 4 molars removed over time! I recently found out that it was broken around that time. (A gift from my former husband.). What is wonderful is that this drug has made me pain free. Question: does this make sense? Is this somewhat typical? Any long term problems with the drug? Thank you for any information. Simonne
