I had very good results with gabapentin, for several years. I never took such high dosages, but did increase the dosage gradually as I needed additional relief, an additional capsule or higher dose gradually. It is a great drug for those who need it and can benefit. It helped me with neuropathy, restless leg syndrome, firbomyalgia pain, leg cramping, other nerve pain, but I began to need to adjust my medications for various side effects. I tapered off, gradually, under doctor's oversight, and now don't use gabapentin any more. It's not what I need to use at this time, maybe my age or whatever. But, my doctor has helped me find the best for me now.It's so important to discuss openly all our concerns and questions with our doctors. I've learned to be open and honest with all my docs. Otherwise, they don't know what's happening, side effects or good effects or fears.....Bless you in your journey
