How long does it take for the effects of Clonazepam to leave the system. I’m referring to the light headed/dizziness feeling.

Variable. The half life is 6-12 hours, meaning that the effects should,be gone from a single dose by then, but th9s can be dependent on other factors such as other medications you take, status of liver, general health, and alcohol consumption. Discuss this with the prescribing doctor.
