I know I have PMT and AF is due at the beginning of next month. I am doing the Isagenix diet (shakes, low calorie, intermittent fasting) and over the past 3 days I am just SO hungry. I crave junk food so eat a small handful of something bad every now and then. I fasted yesterday and felt nauseous on and off all day and SO hungry despite eating the Isagenix snacks (amino acids designed to fill you). I got up this morning, got kids off to school and went back to bed which NEVER happens. What the hell is happening and what can I do??
