Just realized that there is a pretty good explanation for my sour stomach, and it has nothing to do with the Slim-Fast bar.

I made a pot of coffee about midnight. Well, thinking that I should make it stronger than usual to keep me awake, I put in an extra scoop. I didn't realize until it was too late that the grounds were Columbian, and pretty strong already. So the coffee is pretty damn strong. And, to make it worse, it sat warming for two hours before I finally had a chance to pour myself a cup. I'd be willing to bet that it's the coffee merrily eating away at the lining of my stomach that's giving me a bad taste in my mouth.

Only an hour and a half left of my shift. Then I have to decide whether to go to bed, or stay up for a while. Have some shopping to do, and I'll probably end up working 8-12 Fri morning, so I should stay up. BUT.....I'm so tired I doubt I'll make it past 10am before giving in and going to bed. Only time will tell, eh?.....We shall see.
