last time he said he only took "5-10 mg/day, a moderate and sustainable daily dose..."

now he's doubled or quadrupled his "moderate and sustainable dose" but i think we can safely assume he's taking quite a bit more than that. he's an addict showing all the signs of chemical and psychological dependency.
it's sad but that's what happens to people like him.
