The good news is for me, it was more like 2 weeks. Those first 2 weeks were absolute torture. It WAS really, REALLY hard sticking to my new healthy way of eating. But I stuck it out. I did anything I could think of to NOT go off of my plan. I threw food in the garbage, ran it under the water. I journaled, used the computer, drank lots and lots and lots. Kept lots of low cal veggies on hand. Some chicken broth. Hot tea. I kept myself incredibly busy. And I GOT THROUGH IT!!!! And now look where I am.
I knew if I stuck it out, that the end to my misery was near. I also got incredibly excited. I knew every bite of food I turned down would get me one step closer to my hopes and dreams.
But really, it got soooooo much easier after those 2 weeks. HANG TOUGH. It's hard - but no where near as hard as being morbidly obese. Not even close. Please keep that in mind.
You CAN do this. And you will not regret it for a single, solitary second. Good luck.
