Yay!!! Good for you. I found that the first 2 weeks were really difficult, I must tell you. So do your absolute best to STICK WITH IT during this hard time. Whatever you've got to do. Munch on green beans, drink lots of hot tea or water, chew gum - distract yourself with ANYthing - cleaning, journaling, the computer - yup, sleeping.
Once your past this 2 week period it really should get much easier. You'll be much more accostomed to it. The cravings and hunger should subside. You'll be feeling better and more into it.
Hang in there and keep up the good work!!!! Remember it's worth it. It's incredibly worth it. More then you can even imagine.
