My highest dose was a large mug of dark roast made in a french press. One of these in the morning, one in the afternoon. I don't have any idea exactly how many milligrams of caffeine that was, but note that the darker the roast, the less caffeine there is. So I don't think I was even actually consuming very much of the drug. Rather, I believe my body processes caffeine very slowly.
