What the f......

Ok, so I started this week (and today is only Tuesday) with the thought that I would get up early and walk for 20 minutes on my treadmill. 20 minutes is not that long, but I bet if I did it every week day it would make a difference. 20 minutes is not that much less sleep, I should be able to haul my butt out of bed and get on the damn treadmill. I used to walk with a neighbor in Nebraska at 5:50 a.m. Required me to get out of bed at 5:40 (enough time to pee, brush teeth, get on shoes - I wore the walking gear to bed, and don't even ask about how that worked with sex). These days I get up at about 6:45 a.m. I should then, conceiveably be able to get up at, say 6:15 and walk. Nope, apparently not. What the Flip is wrong with me?
