I had the same exact thing last week-all week-the hunger was horrible. By Friday my weigh in day at Curves-I lost 4.5 lbs just last week. I was thrilled but not sure i like those hunger pains. I have never felt like that before-usually when I am going to lose something-I do have a funny feeling in my body-can't exactly explain just different. Then what did I do? fell off this weekend abit-today I feel like I'm almost out of ketosis-my dry mouth is almost gone-thats how i keep track of it. But I climbed right back on today and hopefully caught it before its gone totally.
