Juicing Forum

I tried juicing the other day for the first time. I juiced about 4 cups of baby kale, 2 cucumbers, 2 cup parsley. I made enough juice for my husband and myself to drink but he didn't care for it so I drank the juice throughout the day. That night I had TERRIBLE stomach pain. And now 3 days later I am still having some pain after I eat. The same day I did the juice I had also made a new brownie recipe that used cacao, coconut oil, maple syrup and eggs and vanilla. It was my first time using cacao and they were very rich. So now I"m not sure if it was the cacao, or if I consumed too much juice? Is that possible it was too much juice for my stomach to handle?
