I'm not saying it's something to avoid if you need it, but it does help to have a possible explanation when you know you're doing what you should be diet-wise and have an unexplained jump on the scale.
Even if it's not the real reason, having something to hang it on sort of helps, IMO. I know you can't always figure everything out, but for me, this is one thing that might help me avoid the, "oh well, I'm doing what I'm supposed to and it's not working, so I might as well have a banana split" mentality. That now becomes, "oh well, could very well be the Aleve, so no worries, stay the course."
It's also good to know that it's another source of sodium intake, especially for those watching that.
"If you drop an egg, you don't say, 'Oh, shoot' and drop the other 11, do you?"
