I may have figured out part of my weight loss problem. I've been taking Metformin almost since I gave birth, but I stopped when I got sick earlier this week and never restarted. Since then the weight is really coming off! We'll see if this theory stays true in the coming weeks.
Last week's weight 4/10: 164.8 lbs (BMI 33.9)
Today's weight 4/17: 161.0 lbs (BMI 33.1)
Weekly weight loss: 3.8 lbs
Total weight lost: 19.4 lbs

Mini Goal weight: 141 lbs (pre-pregnancy weight)
Pounds to go: 20 lbs
Ultimate Goal weight: 100 lbs
Pounds to go: 61 lbs

Not bad, eh? Of course I was sick at the start of the week, which helped, but I lost at least half of the weight at the end of the week as well. Yay!
