Sheesh, guys. Pardon me while I climb up on my soapbox.
Nothing wrong with weighing daily if it helps you with your goals, so quit apologizing and using words like "obsessed!" When you look at the habits of successful maintainers, frequent (or even daily) weighing is a tool that supports long term success.
Daily weighing is a tool. For some people it is helpful, for others it is not. But stop apologizing!!
Whew.
(I don't mean to sound too ranty but I see too often posts where people say "I shouldn't weigh myself everyday". Where is that rule written? If it works for you, don't beat yourself up for it! If it causes angst, find another method of checking for progress.)


It has a mind of it's own.
HONESTLY!!! About 2 weeks ago I stood on the scale staring at the dial, motionless, the dial slowly went up as I stood there. In the course of 2 minutes it went up 3 pounds. I have also seen it go down two or three pounds while I stand there.
Well it helps keep me accountable. I also log all my food,

and all my exercise

, so if the scale stalls for a long period of time (1 week or more)
I look at what I have been eating (too much salt, too much carbs?) or goes up slightly
(TOM? more strength training? poor food choices??) I can corrolate those things to tweek my eating work out to keep my consistantly losing.
Each of us have our own tactics that support our journeys.
SCALE
freaked! over a pound or two increase...but, in reality......I already knew those 
forget...on purpose 
bye-bye
