I must be losing my mind.First, I forgot to write my week 15 progress. Second, I'm sure I started writing my week 16 progress — including something for week 15 — twice now, and yet, I still have nothing posted. Ugh.So anyway, despite the fact that I had gained about 1½ lbs for week 15, that's not why I didn't write it. I simply forgot. I think the fact that I had a cold that weekend was a contributing factor.The good news is that for week 16 I lost the 1½ lbs I gained and a bit more, putting my weight at the lowest it's been in about 6 or 7 years. In 3½ lbs, and every pound after, it'll put me at my lowest in about 25 years.That's going to be a major milestone for me.
