I'd say probably not. Almost certainly not, in fact. You didn't say how long you'd been taking the Klonopin...maybe if you have been doing this for years you'd experience some mild withdrawal phenomena, but I doubt it. Best bet is to talk to a doctor, like Kitt said. Preferably a psychiatrist rather than a PCP. Failing that, call up a bunch of pharmacists and see what they say.
