Craving sugar

I’m so confused by Reta. RS Been using for almost 2 months now, and having the worst sugar cravings. The weirdest part is RS has never been a sugar person so the fact that it’s become a craving now is so puzzling. Anyone else experiencing?? RS did break plateau, however, and has lost 3 pounds over the past month… Which is even more strange because they have given to sugar cravings here and there
