why do you need to stop klonopin? it's a safe drug, in my experience has no side effects, gabapentin has few side effects. If you must get off it, cut it in small pieces, smaller and smaller every day, & ask your doctor to help you. gabapentin's side effect that may be bad for both of you, me too, as we age, is its affect on balance. taking it at night only should be fine, though, so long as the dose is low, which it is, so low i doubt it alone will help you sleep. If clonazepam is not helping you sleep anymore, ask your doctor if it's safe to increase to 1.5 mg. Don't increase the gabapentin. Balance problems even just getting out of bed and taking showers can be scary.
