Welcome! If you're really committed, and it sounds like you are, you can shed that weight more quickly than you might think. Use FitDay religiously, keep a reasonable calorie deficit and do some form of exercise. It's worked quite well for me.
Oh, and feel free to join us over in the 100 lbs to Lose thread in the Diet Tips forum, if you like--sometimes it's nice to talk to others who are/were in the same situation you are.
