For me, H.A.L.T. has really been helpful. I know that sometimes a craving has popped up as if out of nowhere, but when I have stopped and paused for a moment...
I have been one of those things..hungry, angry, lonely or tired.
If I am any of these things my brain just isn't in neutral and is NOT doing its' best thinking. I can be just plain whiny and childish if I'm tired..or actually if I'm hungry, angry or lonely too : )
I think it's a wonderful tool to help you kind of "check in with yourself" to see what's going on with you.
