be VERY careful using cymbalta when you are already on neurontin. it literally almost killed me. the newest literature says you should be weaned off the neurontin if you go on cymbalta. please reseach all your own meds and talk to a good pharmacist, doctors DO NOT always keep up on the latest warnings and news.
as far as night cramping, i have been using tranxene 7.5 mg for years for sleep and cramping and i swear by it. joan
