Doing fine during the day until it’s time to go home from work, then SHTF.

I am doing well on my overeating all day while at work. I am busy and I am conscious of my mind and my hunger. However, as soon as I clock off, I feel like a different person comes out and I can’t seem to defeat the urge to stop and get something to eat before I get home and have dinner.

I know I need to work on something here but for the life of me, I am so upset about this that I can’t think straight about what it is.
