Am I losing water weight again?

I was 248.0 on Monday and 247.4 yesterday and now I am 246.0 today.

That's right.

Weight: 246.0 lbs

I'm not going to complain about big losses (well they seem big to me in this span of time) but I wonder if it's water weight again since I wasn't consuming as much last wk and have upped my consumption again since about Sunday.

Though I do find it hard to remember to log my water in my food log when I drink a bottle slowly. Because I can do it in as little as 30 minutes or as long as a couple of hours depending on what I am doing.
