I can get scale obsessed too but, I also know that the quickest way for me to gain is to stop weighing daily. I get into the mess up until the day before weigh in and then I'm surprised at a gain... but that's just me.
a reminder from myself...
I have to fight the tendency of stinkin' thinkin' to give up because I'm not progressing. As long as I am still moving and watching what I put in my mouth then I am progressing no matter what the scale says.
