The only real cravings I've had was the chocolate! I found a LC recipe called chocolate/peanutbutter drops. When I really get to craving I eat lots of protein and fat then have a couple of the Choc/PB drops and it has done the trick! Maybe I'm tricking my brain but it works for me!
Since your cravings are for toast or popcorn try some BBQ porkrinds and a SF Soda. That might help too. It has helped me out in the past! Good Luck and HANG IN THERE, it will pass!
