Ever since the summer after my freshman year of college, I've kept absolutely ridiculous hours--usually going to sleep at 3 and rising at 10 or 11. I mean, it's at the point where I'm not merely awake when my roommate leaves for work at 4:15 AM (he's a bond trader and has to work on East Coast hours), but still very much up and astir. I want to get back to something a little more in line with the rest of the people in my time zone. Is there any alternative to just going to bed 15 minutes earlier every night? I've found that it's very difficult to maintain the discipline necessary to do that, and even when I've gotten on a good clip of doing that I find that one late night studying or writing will completely throw me off.
