Half life of clonazepam in plasma concentration is between 40 to 50 hours. Some lower that value as low as 20 and as max as 60.
The effect of the decrease in dose is individual. As a rule of thump clonazepam starts to act after 1 hour and reach it's max pick in about 4 hours. It's effects last an average between 6 and 12 hours depending of the individual.
Nobody can tell if this values can apply to you. It's only a reference from manufacturer information and medical experience.
Psychological and physical conditions affect how this numbers play on you.
In my experience, is primordial to have a plan, stick to it, tweak it as the time goes by and be less obsessive about what others do.
Hope this help you!
