Ummm. Pretty close. 3 pots of coffee - poured over ice - from about 4am ~ 10pm or so? I tend to pretty obsessively sip during coding sessions. Although as I have aged, I have noticed that it might be disrupting my aging sleep patterns, so I may need to start cutting it back. But, in Japan, in my youth, when I was working in semiconductor - people considered it excessive, but not extraordinarily, you know, extraordinary. (I didn't drink or smoke at the time - now I do - so I think the combo is ganging up on my biology's ability to support this scenario)

EDIT: I was thinking about this a bit more... The first pot is 4am~6am, the next is 6am~10am(or so), and the 3rd pot is nursed over the next 12-or-so hours). I guess I am bootstrapping the system pretty hard at the beginning of the day... I haven't done a cost-benefit analysis, or even thought about it much, but looking at this conversation, it might turn out to be more cost-effective to take up meth (just kidding, that stuff sucks. Coffee is smooth).
