Every person is different... I'm with Jenny, I eat something sweet but definitely lc very often.
But, I'm also in this for the long haul and am not discouraged by slow numbers. Also, I'm not having problems with major cravings, so you have to see how things are working for you.
My dh has been endulging in the lc ice cream lately, and was telling me that he felt like he should stop eating it the other day, and I told him that even on the most absolute pig out day of low carb treats, we're still only having a fraction of the amount of carbs we would've had on a normal day before low carb. It's all in how you look at it, and whether or not you think it will make the cravings come back... for me, I wouldn't even sneak one french fry, because that would be my downfall. But lc cheesecake every night for a few days... no problem.
