Clonazepam is a benzo and they need to be tapered off very slowly. You should go see the dr that Rx them to you and explain that you wanna stop it, establish a tapering plan, stick to it and go from there.
Here's the link to a site which is the reference in benzos:

Slowly and under a doctor's care.
