Hello Verona,
Prior to having a family I did the 3 days of apples a couple of times a year, really helped me... I did not use it to get out of flares, used it more to heal intestines and improve digestion so I could stay on No Starch Diet as I struggled with energy early with diet.
The first couple of times I did the fast, experienced headaches from the release of toxins most likely in body. I usually started 3 days of apples on a Friday and took it easy on the weekend as completed the fast.
Here is a link:

Regards,
Tim
