Speaking too soon

I was happy last time about breaking through the plateau, but then overnight I gained back two pounds and there the scale stayed for the past 3 days. I know there are all sorts of variables--water weight, muscle gain, etc. And I know some people would advise not to weigh every day. I personally am a fan of doing it, and apparently weighing in "at least once a week" is one of the things successful losers do. 

In the past few days I've been really trying hard to drink enough water (at least 64 oz. per day). For the past two days, I've had fruit for breakfast. I don't know if that had anything to do with it, but today the scale was back down to 185 (9 pounds lost). Even if that's all I did for the entire month, that's still pretty good. I feel like I have a few more pounds that could come off, but time will tell. I would have liked to have lost 15, since the first month is usually the easiest, but this is fine, too. 

I think it's important to use the scale as the tool it's meant to be, but not to get too hung up on the number. I'm wearing pants I haven't worn in months, so that's a good sign. A coworker said I looked like I was slimming down, so that's nice, too.
