Lose 10 pounds

I was doing good with my plan to lose wieght but lately I have gotten stressed and feel into old habits. One thing I did was went back to Mountian Dew.I had given up for almost 2 months and now I am backing to drinking 2 cans a day.I am going to switch back to coffee in the morning and drinking water and green tea the rest of the day. I think baby steps will be the best way to develop better eating and exercising habits. I have too many bad habits to try to change all at once.I just get frustrated and give up.
