Hi and Welcome,
Yes, it is hard, really hard and I don't think there is any way to do it, but to stick with it and do it. It's really that simple. Do whatever you need to do to take your mind off things. Get outside, exercise, listen to music, call someone, watch a movie, anything to take your mind off your cravings for a few minutes.
Hang in there, it gets easier as time goes on.
Anna
