I also have been taking Klon long term, without a lot of remaining sleep benefit, but a two year withdrawal was so hideous (I stopped sleeping almost completely, among other scary things), I just couldn't do it. My doctor, who had been pushing me to discontinue, changed her tune when she saw my deterioration. Long term daily benzo use is not good for us, I think we've established that. Neither is long term sleep deprivation. So we take a drug that no longer helps with sleep, to avoid a total lack of sleep. Feels to me a lot like being caught in a trap. I've
taken low dose 100 or 200 mg gabapentin. It was the only of many meds that helped me with sleep during K. withdrawal. The sedating effect lasted for 1-2 months, our bodies will find their way to homeostasis by adapting to the effects of ALL sedating drugs sooner or later. For example, my sister takes 1500-2000 mg daily for spine pain and has zero sedation, because her body has adjusted to its presence. I couldn't go higher on gabapentin because of side effects, and that drug itself causes a nasty withdrawal. I had to liquid taper from 100 mg, ridiculous, but I am extremely sensitive to meds, and it was the second time around with gabapentin, which can make discontinuation more difficult. So you may not have this problem. I did notice the one time I got up do about 400 mg very briefly that it made me really wobbly - drunk feeling - in my legs. These drugs both have the ability to affect balance, so watch out for that.
