So basically after any sort of workout my mental focus and clarity goes out the window for at least 3-4 hours afterward. But seeing as how I have a freaking doctoral dissertation to write, this is not a good thing. My ideal schedule would be to get up in the morning, go to the gym, run errands while I'm out, then hole myself up in the apartment and work the rest of the day. But this is not working. What can I do to ameliorate the situation, apart from working out in the evening? (which I prefer to not do - I have a gym right across the street from my apartment and would love to take advantage of the uncrowded weekday hours.)

My eating schedule is as thus: get up in morning, have coffee, eat when hungry (usually ~3 hours after waking up, or right after my workout, if I do a morning workout that day. The usually 2 more meals throughout the day.)

I *AM* a morning person, if that makes any difference.
