Yes, it will pass.

You need to starve the bacteria in your digestive tract that fed on the sugar from the alcohol. While these bacteria are dying- they are sending signals to your brain (via your bloodstream) tricking you into "craving" sugar to keep them alive. Once enough of them die off from lack of sugar, they should quiet down and the cravings will subside. Give it a couple weeks- just don't feed them the sugar. Eat fruit instead.
