The good news (which you probably know) is that the carb cravings fade quite quickly.
The bad news is that you have to stop eating the foods you are craving, and cut down on carbs. Otherwise, the cravings keep coming.
Do you have a blood glucose meter?
Getting one had an incredible effect on me.
Actually seeing what awful blood glucose rises were happening when I ate certain foods... well... it keeps me on the straight and narrow.
As a tip, the only thing that has ever killed the cravings for me is fat. Fat bombs, cream in coffee, a fry up (no bread, of course), steak and salad with mayo, proper food. filling. rich in fat. That will get you through the first few days without carbs, and squash the cravings. As
@jack412 says, it only takes a few days.
I really do understand. People who don't get carb cravings have no idea, do they?
