The bulging tummy conundrum...

OK...so like the past 6 years or so my tummy just seems to keep growing. I know I'm not pregnant because if I were, that kid would've spewed out of me a few years ago! Can't be the whiskey...I don't drink that much, after all (regardless of my reputation)...and I pee way too much for it to be that. Is it just a middle age thing? I really don't eat much. Although when I was younger I could eat a Greyhound bus on a daily basis and was abnormally thin. I guess metabolism changes as we get older...which totally sucks!!! I so miss being able to wear 29 inch waist jeans. :(
