Yes, it does get easier. You can't break an addiction in two days
People's experience varies. I didn't suffer from those kinds of cravings, so I can't help there, but I hope others that did will join in.
It is hard at first. My road has certainly not been smooth. I was a pure carb eater -- my diet was bread-centered. Part of it is changing habits, I think. I resented having to be so conscious of everything I ate. But every change is positive and it DOES get easier. If you want to lose weight, you will do this.
As for never eating another chocolate again? It depends. Many people here have a "day off," either because of stress or holidays or whatever, and then get back on track easily. Many lose their taste for sweets (yes!) and others lose weight and include MILD indulgences of sweets in their maintenance plans. But if you are a true sugar addict, that may not be a good idea.
We have to change our lifestyles and our eating habits, because otherwise, there is no hope of not being fat.
What you can do.
1. Make lists of low carb foods that you really really like. Remember that butter is allowed, as is salad dressing. You can keep the skin on the chicken and eat the fat on the beef. I make lists of meals so that I have something to draw on when I can't think of what I want to eat.
2. Keep low carb snacks around and get rid of any high carb snacks so that you have no excuse to take the easy way out when stress or hunger strikes.
3. Make sure you eat enough, 10 to 12 times your weight in calories. If you're well fed with good food, the chocolate may call your name, but you'll have the strength to say no.
Good luck. Be sure to check the links that Karen has put on the Newbies thread. There's lots of good info there.
