You can not overdose on benzos. Get very sick yes. A little alcohol is ok. But surely you did not mean 10mg of klonopin? I think perhaps you meant 1mg which is a significant amount. It only goes up to 2mg and usually they start you at .25 or .50mg

The real danger here is dependency and addition, or worse, you get in a accident because you will be very impaired and your balance will be off and your reaction time will be slower. So this could result in harming yourself or others.
