About 2 yrs. ago I went from 134 to 117. I am 5'6" with a medium frame, so I was too thin. I didnt have my cycle for over a year. I got to a certain point were the binges were too frequent (about everyday) finally i started gaining weight and went back to a healthy weight. My cycle started up again (never thought I'd be so happy to see it) and I realized the binging was happening because my body was literally starving....it just wanted food!!! I had always had a problem with binging, but after getting to such that low weight it magnified an already existing problem. Your body is craving because it is starving and you aren't getting your cycle for the same reason. This is JMHO and I hope it helps ya out. Good luck to ya!
