Hi, I started many years ago (about 10) with 300mg of Neurontin 3x a day for PN. I now take 1800mg per day, 300mg with breakfast, 600 in early afternoon of the generic gabapentin, after driving is done for the day (am retired), 300mg. at dinner, 600mg at bedtime. This does not relieve all pain, but makes it possible to function somewhat and sleep at night. Weight loss is really hard, my thinking is slow, too much "foot-time" near bedtime still causes too much pain for sleeping.
