i quit weighing everyday. Because weight flucuates so much, depending how much salt you ate before. An important tool to weight loss is the tape measure that is the true sign of really getting smaller, and the way your clothes fit.
I weight every day because I like to see how it looks in the graph in BalanceLog. I just have to remember not to be frustrated by the ups and downs. Plus even with the ups and downs, if I am below the guide line on the graph I know I am ok.
