I have that frame of reference because I abused caffeine pills. I would carry them around in an Altoids container because they went down a little easier with a coating of Altoids dust. They were 200 mg apiece. I only exceeded two in a serving once and regretted it intensely, then failed the final for which I was attempting to cram. A two-pill drink is bonkers, and at Panera? I don't understand this place any longer.
