I'm Not So Happy...

I don't know why, but I just can't get motivated right now.  I know what I should be eating and everything like that; but I'm just not doing it.  I more than want to lose weight, I NEED to lose weight.  It's important to my future health.  I also don't want my kids growing up with a fat mom.  I've always wanted to be a MILF (lol) but I can't be that looking like I do.  I've looked into doing a detox thing; but I've so far read several articles on webmd and yahoo health that pretty much say they're not so good for you.  My biggest vices are Coke and sweet stuff.  I have a CRAZY sweet tooth and it gets me into trouble pretty much on a daily basis.  I can also drink about 2 cans/bottles of Coke a day.  I am addicted to it.  I really wish there was something that was just  as sweet and tasty as cake or my mom's icing that wasn't so fattening.  I guess I should try to eat more fruit maybe?
