This is my third cycle on PB. With every cycle it seems that my carb cravings (mostly sugar) are getting worse. THis time it seems to be putting me back into carb flu like symptoms. headache, shaky legs,wanting to eat anything with sugar,uncontrolable hunger. I have upped my carbs , banannas, sweet potatoes, plantain chips, during this time trying to combat it. Unfortunately, this lasts about two weeks. The rest of the time I am fine on a low carb diet, in fact I prefer it. So I guess what I want to know is, can PMS send you into Low carb flu and can eating carbs during this time, sabotage you in the future and cause the same thing to happen again?
