How often do you weigh yourself?

Daily.  Unless it's the holidays in which I avoided the scale for three weeks 

I enter my weight in My Fitness Pal, along with what I eat.  If seeing normal variations will cause you stress or depression, then don't weigh yourself daily.  If you can recognize and accept that fluctuations will occur, then daily can be helpful.

I sometimes weigh daily which I probably need to stop!! I am planning on changing to once a week.
