Well, I wouldn't want to rely on Klonopin for any length of time if you can avoid it, as it's addictive and very very hard to stop taking. And eventually it will probably stop helping you sleep and you'll need to take more of it and so on. But that drug is relaxing you, so it's possible you are suffering from anxiety. I don't know, you don't say if you're an anxiety sufferer. You could also have a GABA problem of some kind, as that drug acts on GABA. As for your heart rate going up and palps, that can be a sign of heart problems but it is also a symptom of anxiety.
