Once, Twice, Three Times a Loser

I lost 3 things on the weekend. I lost my appetite. I lost some weight (presumably the result of my appetite loss). And I lost somthing else too. I'm not sure how long I can last without it. The appetite-loss and weight-loss I can deal with. But this is not something I can afford to lose, especially now. Oh well, I'll give it a couple of weeks. If I don't have it back by then, I'm gonna be in real trouble.
