What? Can't be!!

Okay so I have been trying to lose weight. I have been watching what I eat & staying active.I even walk to the liquor store & the Olde Towne Market (they have McConells)..I gained two pounds yesterday! I was trying to figure out why?...I had pineapple, a banana, three tootsie pops, two Jack in the box tacos, a Queen Burger from Charlie's, two bloody Marys...stupid banana.
