Starting again

As we looking into trying to conceive a child, I need to lose weight for a number of reasons. I didn't realize it's been since Oct 2009 since I last even bothered trying to lose weight. Starting on Saturday, I am going to try and eat healthier and exercise. I'd *love* to lose about 15-20lbs before my next GP doc visit for a bp/blood check. That's not an unrealistic goal, it's in the 2-3lbs a week range. This isn't going to be easy and I have horrible will power. Thinking about joining a message board for some support. I would love to do weight watchers, but buying healthy food is expensive enough. I think I'm actually looking forward to trying to lose.
