FourMe - Anti-Food Days

I've discovered that I can only eat 2 weeks of the month! Eat eb ma3na eny akil eb thima w thameer. You might think I'm insane but honestly I feel the urge and crave food only when I'm pms'ing well in my case when I'm Pmdd'ing. Otherwise I don't crave anything, in those 2 weeks I gain weight and come the 2 weeks after I stop eating and start losing what I gained and the cycle goes on :/ Heeeeeeeeeeeeeeeeeelp..
