It very well could be the alcohol that is causing them to have these cravings. I was never much of a sweet eater but instead I loved my salt- chips, pretzels, doritos all that yummy stuff and I have not had any cravings for these at all. Unless they are having the low carb chips or things like that, I find if you have those you will crave the real stuff, it happened to me the last time so I have stayed clear of them and now I am doing just fine when I go down that junk food isle in the supermarket. I hope they hop back on the wagon and you don't lose your LC buddies. My best friend is my LC buddy and we check in with eachother everyday sometimes more than once and encourage one another., Good Luck I hope everything works out
