going back to my old weight

Argghhh I;m having a hard time going back to my old weight. I guess because it was a third baby it's harder for my body to go back to the pre pregnancy weight. I've tried dieting which failed because I cannot live without my carbs hahaha then I started exercising but the girls kept on calling me so that didn't work maybe I should try weight loss pills and see if it'll work on me. I just need a about ten lbs to lose so hopefully the pills can help me attain my weight goal. Let's see what happens.
