Craving chocolate the day after?

I just had my second session and boy was it a doozy. I was so drained I could barely move for six hours. I just laid in bed with a heating pad with the lights down low and watched relaxing videos on YouTube. The fatigue was WAY more intense than my first session.

One thing I noticed after both sessions was an intense craving for chocolate the next day. I don't usually crave sweets, but I pounded a bag of Resse's mini cups after my healthy veggie dinner and now I have a stomachache.

Does this happen to anyone else?
