Chocolate. I remember when I first began paleo in August 2012 and realized I couldn’t have sugar. It was devastating, but when I cheated (even a little), my hands became claws from the effects of RA. This was real motivation NOT to have any type or amount of sugar–even dark chocolate with its negligible amount of sugar.
I am happy to report that 2 years later, 6 months into killing off my candida, and several months into killing off my camyplobacter/clostridia populations, I am now able to taste a tiny bit of chocolate without disastrous results to my hands. I just had to do the experiment and it was worth the wait. Associating chocolate with pain is not a healthy thing.
