What does untreated hyperthyroidism feel like?

Ask Vodkapundit, aka Stephen Green:

I started losing weight a few months ago. Nothing serious, just enough to get friends asking if I’d lost any weight. I denied it at first, but then I had buy all new Levi’s in a waist size I hadn’t worn since the late Eighties.

I won’t spoil the ending, just read it.
