Two steps forward, one step back! Keep on keeping on. The only difference between try and triumph is a little umph and you are showing you have plenty of that!
Congrats on the four pounds. Good job and you will get below 300. Just don't give up. I was trying to get below 200 by the end of last year. It did not happen but it will soon cause I am working harder this year. My want to reach my goal of losing 60 pounds or more this year.
