Whole30 challenge

Ok so Im starting a new personal challenge to try and get my food in control.  I am a horrible horrible snacker and it is rarely on good stuff!! About  4 months ago I cut all drinks out but water and have stuck to it 99%.  Every now and then when we arent at home I will take a sip of the girls soda if I dont have any water and Im dying, but other then that I am doing amazing.  It is crazy how I used to want soda a and juice all the time and now it makes me sick to think of drinking it.  I am really hoping my new challenge will help with the sweets part! So I found this thing on pinterest that is basically clean eating but its called the Whole30 challenge.  Here is the low down..... YES foods: meat, eggs, veggies, some fruit, and nuts. NO foods: sugar, grains, legumes, PB, and dairy.  It sounds dang hard to me but I am going to give it a good 100% shot!! Wish me luck, I hope it works! Its only 30 days right?!
