Junk food rut.....

So ever since I came home from my vacation, I have been in a junk food rut. I will think "your gonna be good today Melissa, & before I can reach the end of the day I have ate some type of junk food crap. It's really starting to disgust me that, I can't seem to shake this habit the last 2 weeks. I want to loose more weight, not maintain or gain for goodness sakes. Ugh...can someone lend me so willpower because apparently mine has left the building. Work has also been, very stressful the last 2 weeks so I don't know if that is playing into my issue or not. I really need to just get my act together, where is my determined Melissa....I need her to come bak ASAP! Lol. Does anyone else have this problem?
