Im at a stand still

I havent lost any weight in over a month. Good thing is I havent gained any. Walking far in the dark has not been apealing to me. That means lack of exercise for me and the pups. Ive been doing 2 mile walks on demand and playing xbox biggest loser. I havent touched diet soda since July and I generally only cheat one day a week.There were so many parties the last few weeks and I didnt touch a thing that was bad, unless it was my cheat day. Does anyone have any suggestions at all to get this weight loss going again? Im at a stand still and its frustrating!
