You are implying that you've only been using the Clonazepam (Klonopin; Rivotril) for 1.5 days? If this is the case, then you are unlikely to have developed a tolerance of any significance. There is a difference between what I call chronic tolerance and acute tolerance. Chronic tolerance, if you will, is the dependence/withdrawal cycle that we are most familiar with. The acute tolerance, again, if you will, is the label I apply to the phenomenon in which use of a drug in rapid succession before the effects of the previous dosage have worn off, leads to a sensation that the effects of the drug are blunted.
Think about when you smoke Cannabis. It's much more enjoyable to smoke, wait until you are completely back to baseline and then smoke again, as opposed to just smoking joint after joint every 15 minutes. In short, you aren't getting the full hit from the drug that you might be expecting when you use them too rapidly.
