Numbers for the New Year

Well I said I was gonna be honest about my weight, sizes, etc.  On this first day of 2012, I climbed onto my scale and then I peeked to see what the numbers said.  Thank God it didn't flash ERROR and quit on me.
SO......today's stats:
Weight:199 lbs
I also bought a pair of black pants today and the size was an 18.

So what is my goal you might ask?  I would love to lose 70-80 lbs over this next year. I am only 5'2", so 199 lbs is a lot of extra weight to carry around. That seems almost unattainable, but I know I can do it!!!!
