I'll be joining you girls from now on, seeing how I'm finally ready to take control of my weight!

I'd like to lose about 15 lbs and do some toning before my first fitting, sometime around April or May. I've been improving my eating habits with green smoothies for the last 3 days and I already feel a small change in my energy. Pretty pumped about that in fact!
Anyway I'd like to keep some track of my calories. There was a site I used forever ago but can't remember which one it was anymore. So tell me, which site is your favorite? Preferably free of course. ;-) TIA!
