I was the same way on my first three days. I almost felt like I had fever and the sleeping was horrible, but that will be gone in the first three days. I did another posting and I just had someone reply and let me know that salt is not good at all, and I have been seasoning everything with that so I am sure that is what my problem has been. For you it might be that you gain a lb. or two the first few days, but if you are like most people it will start falling off somewhere around your 5th day. You should at least notice the fluid coming off. You will also find you have to go to the bathroom constantly. I don't worry about anything like cals, fat,etc. I just count my carbs, I don't need anything else to constantly think about.
