Losing 50 lbs.

All through out high school I have always been within 130 lbs. I met my husband and within a year I had gained 30 lbs making me 160 lbs. After 4 months of being married we got pregnant and I gained 40 lbs but lost that pregnancy weight. Not long after we got pregnant again and I gained 42 lbs with the second pregnancy. I only lost 20 lbs after having my second child. He is now 16 months old and I am still a little over 180 lbs. No more excuses! I need to get my butt in gear and lose these 50 lbs that are lingering. I feel uncomfortable in my own body. I don't feel like myself anymore. I have no energy. I am tired of clothes being too tight and not fitting correctly. I want to look the way I did when my husband and I first met. I want to be healthy. I am going to start drinking only water, watching what I eat, playing more with my children, and working out Monday through Friday. I hope and pray this works for me because I'm not happy with the way I look or feel. I'm going to be doing cardio and toning work outs. Let's wish me LUCK!!!
