Haven't had a chance to read all the replies to this thread yet - but didn't want to wait to give you a hearty congrats on decided to take charge of your weight! I know how hard it is to lose it, and have recently lost 100+lbs. I will be more than happy to support you in any way that I can! Sadly, I don't have twitter though, but I do have facebook!

I don't know you, but I am very proud of you! I look forward to following your journey! If you ever want somebody to talk to about it - my ears are always open for ya!

Not sure if anybody has linked this too you yet, but http://www.livestrong.com/ is something that I used that helped me lose most of the weight. It even offers a blog feature! You can track your weight progression, your calorie intakes, along with your exercise on it and much more.
