I think it all depends upon the dosage you are advised to take. I was on a very large dose of Gabapentin for many years and it worked really well, especially at bedtime. I know this as when I finally stopped the Gabapentin in order to have a nerve stimulator fitted, the pain returned in a powerful way until the nerve stimulator took effect. It appears that Gabapentin works for some and not others. I initially tried Lyrica (Pregabalin) with near disastrous effects including being suicidal. Yet other folks have had success with this drug. I guess your doctor might assist with a change of dose, and perhaps the lack of sleep and anxiety might not be associated with pain.
