I lost about 15lbs. I'm 5'4 and went from about 135 to 120.
It was a combination of the following:
-I got rid of the alcohol calories
-No more eating junk when I'm drinking and/or hungover
-I workout 5-6 days a week and make healthier food choices. I'm now addicted to cardio.
The only downside to all of this is that I need to buy new clothes...well, if you can really consider that a downside...haha.
