Where's the rest of me?

I spent Thanksgiving night with a couple of friends. Good time. When I was close to leaving, the wife told me mentioned that I had lost a ton of weight. Another friend of mine said about the same thing a couple of weeks ago. Both times I reacted with surprise, because that's not really something I've been trying to do. Maybe stop gaining at a noticeable rate, but even there I wasn't too conscious of it. Having acid reflux there are a few dietary changes I've made, and they may have had side effects. But really it just sort of crept up on me. So I guess the key to weight loss is obliviousness.
