I agree with Matt. People who truly gave up on or decided they didn't thrive on ancestral eating probably stopped visiting PH once they were sure their decision was final.
I had a "crisis month" about 4 months in and I did ask myself whether it was worth it to give up all my traditional snacks and high-reward treats. It's probably fair to say I gave in, too, because I had 2 binges in month 5. I stopped visiting ancestral sites, including PH, and I went out and bought a huge supply of junk.
A funny thing happened, though. None of the wheat-based foods tasted as good as I thought I remembered and they made me sick. Other binge foods didn't make me flat-out sick but the taste and after-effects were still very disappointing compared to the memories I'd been carrying around.
So, what happened is that I found out once and for all that the manufactured food-like products had lost their grip on me and I had no reason to binge. I haven't been mildly tempted since that time (August) and even on days in December when I had a neolithic treat like ice cream or chocolate the "treat" was never the best tasting food I had that day.
Now my experiments and treats are all safely within the realm of ancestral eating on a day-to-day basis. My wild monthly splurges are something like hard-shell tacos with a few forkfuls each of rice and beans. :O They taste good, there are no negative consequences and no regrets. Foods or food-like products that can't meet that standard are not included even as splurges.
