I typed in 6 mg of klonopin and see that it's kind of the standard amount for party pigs with a tolerance for benzos. I remember an earlier post of Hugo's in which he said something like "... klonopin (yum!) ...", so he likely has a tolerance for that stuff.
As a side note, I also read that klonopin causes amnesia in a lot of people, like blackout drinking.
In any case, Hugo has some weird thing going on right now in which he seems to crave punishment - he is saying that he will appear as his own lawyer and plead guilty. I really doubt that after people make him aware that he will spend a minimum of 1/2 year in jail, have his driver's license revoked for a minimum of 4 years, pay a fine and have a felony conviction on his record. They apparently take felony DUI seriously in California.
And then, he may be making all of this up. You have to remember that every word that comes out of Hugo's mouth is for manipulation, and it only sometimes coincides with actual facts.
