Hi Mary, I've done both ways...if I really, really fall off the wagon and eat myself silly (and sick), then I do a day or so of primarily liquids (tea, water, juice, broth soups) and that generally shoves me back on track. If I've just been not-so-good, as opposed to horrible, I'll go back to one of my food logs in the beginning, rather strict, but not a crash diet, and follow that for a while. I agree that tightening up for a few days really does get the cravings and the yuck out of your system and makes it easier to be smart about what you choose going forward.
Notice I can say this three days before the biggest food holiday we have here
