Are you SURE it was 1 mg? I'm asking seriously here.
I'm assuming you are an average American male, possibly a little overweight, so 1 mg of Kolonopin (assuming you're a regular user), will be filtered out of your blood stream within a few hours if taken in the normal dosage. If you took it all at once, you'd pretty much be sleeping most of the day, as it is a drug designed as a sedative and anti-siezure medication.
