While in NML (meaning I had already accumulated some tools to deal with the craves), many times this saved me: when a crave hit, I would start smiling and thinking "oh good, another crave, another proof I am becoming an EX". And I kept smiling and telling myself over and over the same thing, till it passed.
Read about NML, and learn to "ride" the crave, don't fight it, deep breathe through it, welcome it, knowing it won't last too long. Doing so, you won't be exhausted at the end of the day, but happy you have another DOF under your belt!
Happy quitting!
