I will be the biggest looser

So the hospital that I work at will soon be starting up a Biggest Looser competition from January 12th to the end of May. On staff will be a dietitian and a personal trainer to consult with. Whoever has lost the most weight in that time frame wins $300. I plan on participating and believe that I have a very good chance at winning. For me this means I need to get my will power in check, I need to cut back on the oh-so-loved sweets and cut back on soda. I'm not too worried about the soda part considering that all I drink at work is water, I just need to drink water while at home. I am however worried about the sweets part...I am very aware of my sweet tooth and know that it has gotten me in trouble. I just need to kick it in the butt and buckle down. Even when the competition is over if I am not the winner I know I will still be a winner because I will have tried. I hope everyone that reads this will help to be a support for me, I know I will need it. Words of encouragement will be much appreciated. Happy New Year everyone!
