with me, my morning condition almost always depends on my mental attitude about the day. if i have something interesting to look forward to, even after being up drinking until 3 on a sunday night, i can jump out of bed. it's the in between days that kill me. if you know you're just going to have to "ride the day out" those days are the worst. i usually go out for drinks on thursday nights and don't get too much sleep, but it doesn't matter because fridays in the office are always easy days. i have also learned the fine art of the after work nap - used to perpetuate the stay out late/get up early for work drudgery cycle.
