That's fucking awesome, bro, I really don't care. Nobody takes 500mg of Ritalin all at once. You're asking for trouble when you do stupid shit like that. I know people who've been on Ritalin for months; even with their tolerance level, they still only do about 260mg in a day.
I don't like drugs , drugs like me
I can do an all-nighter without any drugs
I've been up all night no drugs.
