You will lose a lot. I lost 35 lbs last time I did it. Honestly you have to get in the right frame of mind- soda is a huge no no. I will not lie the first few days are hard but once you get going the success feels so good and motivates. Go dump the coke down the drain - clean out your fridge and cabinets, have some smooth move herabl tea, and start thinking postive. You cant say i like to eat and wont be able to do this. You have to start saying I will do this and no food taste as good as being healthy. Let's do this - you will feel so good!
