Thanks for asking this! I recently began a juice fast of sorts... I have been using the recipe from the movie " Fat, Sick, and Nearly Dead", and then in the evening eating a meal of 5 ounces of meat protein, a large salad, and a vegetable ( steamed). I ate out with family, and when I was finished eating the food served at the restaurant, I was very sick feeling for about 2 hours. I knew that it was the food, and my body had not liked it. I thought it was just me.... it also happend when I go grocery shopping and I get near the aisle that has all the room fresheners.... man, I can't stand the smell!! Instant headache. thanks again.... I appreciate all the info here on this forum and read it daily, but do not contribute... you are all too smart for me!
