It's not going to be like that everyday. Just get through the first week! If you have ever detoxed your body before, you'll notice they are the same feelings. If you find your headache lasts to a second day, take some Excedrin or Tylenol. You have to keep in mind that all the not-so-healthy foods eaten in the past are stored in some way in the fat. Since you are releasing that fat, all that stuff is going to be floating around in your system now. I was icky my first week. Even vomited twice. Then was perfectly fine, energized, and happy on day 9. Also, you might be experiencing withdrawal symptoms. Your body was used to constant sugar highs and carb highs (and caffeine highs if you drank a lot of caffeine). Now, it need to learn how to function without them.
