Sooo sleepy

I'm already looking forward to my afternoon nap. One of the highlights of my Xmas vacation was sleeping in, napping and going to bed fairly early. I suppose sleep isn't the worst thing to be addicted to, but its getting old. Some combination of medication and stress has zapped my energy. Maybe it's because I haven't exercised in the past 6 month, I've been too sleepy to leave the house after work. Maybe I should take my vitamins, too. All I know is that coffee seems to have the ability to sooth me to sleep like warm milk. I don't really mean that, I think milk, especially warm milk, tastes gross, so its more of a wake-up than black coffee. Why do I love bitter ( I also love sour drinks) tasting things?
