Sedated, maybe worse: 5.5 mg of Clonazepam is an overdose for almost anyone, & would likely result in deep sedation (unconsciousness) for a number of hours, & possibly respiratory depression. While not likely to be lethal, it could be. In an emergency room, the patient's stomach would be lavaged ("pumped") to remove undigested pills, an antidote given, & a psychiatrist would evaluate the apparent suicide attempt.

Don't know.: This is more than six times the recommended upper dose. It likely will not be fatal, but it is definitely not a good idea.

For seizures it is approved in doses up to 20 mg per day, more than you took. But you are going to be tired, staggering, experience spaciness and slurred speech. Don't drive for several days. Then, in the future take the medication as prescribed.
