How do you crush cravings?Especially during the first few weeks of your new lifestyle

Hi all, the title of the thread is pretty self explanatory. The two things that have held me back from reaching my fitness goals are 1.) CRAVINGS and 2.) EMOTIONAL EATING. I have decided to join this forum because I am ready to take accountability for my eating, and I believe that having SUPPORT from others will help me do that (I have very little support at home. My spouse is a handsome man who eats whenever and whatever he wants. At this point, I don't think he even believes me when I tell him that I want to lose weight). Anyway, I have tried substituting healthier habits for the emotional eating, but EASIER SAID THAN DONE. I know what to eat, I know when to eat, but for some reason, the cravings always get me! What helped you make it through those first few weeks? Because I know that they are always the hardest. Once you start seeing results, it is easier, but I need help for making it past the first few weeks/few months. Thank you in advance!
