It's withdrawal. Just thinking about Klonopin practically makes me pass out with fear - remembering what it felt like cold turkeying (lost insurance & job) after having taken it for YEARS. Sleeping - maybe - 2 hours a night for a straight month. Aagh - I can't even talk about all the other awfulness. Never never never again.

What others have said makes sense: you may want to go back on and taper excruciatingly slowly.
