Hi there and welcome. Congrats on your upcoming marriage.
As far as the eliminating cravings goes, what's always helped me was to cut it completely from my diet, but that's just me. It's tough for the first couple of days but once you get past that it's smooth sailing. My favorite part is when I go back to that food after a few weeks and it tastes awful. Then I know I have that control over that food instead of it having control over me.
