Carb addiction can totally drive you bonkers, can't it? Whenever I've fallen off the wagon, it takes sooo much willpower to stop eating the cr*p again, it's like a physical pain. I've learnt not to judge people who are trying to come off addictions, whatever it might be ...
Even worse than the cravings or the physical stuff is the mental cravings I get from time to time, months into low-carbing :-/

I hope Met will help you again!!
