just doing some reading about clonazepam :

it is used to treat seizures

it is a benzodiazepine used in seizure disorders

tolerance to antiseizure effects develops with long-term use

abrupt withdrawal may precipitate seizure activity or status epilepticus

Withdrawal symptoms may be caused by the abrupt separation of benzodiazepine molecules from their receptor sites and the resulting acute decrease in GABA neurotransmission. Because GABA is an inhibitory neurotransmitter, less GABA may produce a less inhibited CNS and therefore symptoms of hyperarousal or CNS stimulation. Common manifestations include increased anxiety, psychomotor agitation, insomnia, irritability, headache, tremor and palpitations. Less common but more serious manifestations include confusion, abnormal perception of movement, depersonalization, psychosis, and seizures.

Toxic effects of benzodiazepines include excessive sedation, respiratory depression, and coma.

Adverse effects of antianxiety medications include paradoxical excitement, anger, aggression, and hallucinations.

Some drug interactions occur when antianxiety medications are taken with alcohol or sedative-hypnotic drugs - these combinations are hazardous and can cause respiratory depression, coma, and convulsions.

Caffeine, nicotine can decrease the effects of antianxiety medications (CNS stimulants - also includes antiasthma drugs, appetite suppressants, bronchodilators, nasal decongestants).

Not sure if this is helpful re: the experience you are having.
Hope it is at least informative.
