The first thing I do is get on 3FC to refocus. It has helped me in the past though I'm not home alone much now, before I was a SAHM so I needed to stay out of the kitchen. I also chew Extra Speriment gum, it helps and drink water. I find that if I put 4 bottles beside me it will definitely help.
... don't think about tomorrow, focus on TODAY and do the best you can//I'm not where I want to be, but I'm sure not where I used to be!//Don't let a bad meal turn into a bad day, a bad day turn into a bad week, a bad week push you to give up, Just pick up from there and get back on track
