on my way down

I just spent an hour on my wii and feel really good (sweaty) but really good, I am trying to keep track of all my calorie intake and subtrack my calories burned on the wii. so far today i have consumed 728 calories and tonight on the wii I have burned 345 calories.  and no more diet soda for me, I am drinking water with lemon.  Its really good.  I know I can do this.  need to be a size 12-14 by end of sept for my nieces wedding.  really for myself so i can do the hard uphill hiking with my husband and so i can carry myself better so my daughter knows how to eat and exercise and to find that balance.
