Sir, I have been taking the recommend max dose of Gabapentin for several years now. That max dose is 3600 milligrams. If you are taking 100 GRAMS I believe that means you are taking 100,000 milligrams daily. I am not a doctor but you can look this info up if you have a smartphone or computer. It sounds to me like you are taking 30 times too much. Perhaps this is why you are have these problems. John Maccorkindale
