Sounds like the acid in the LJ caused a bunch of gas! I wouldn't worry about it - doctors cannot help you here. Fasting creates many different types of cleansing crises, and food will not solve them. More water, drink the regular lemonade formula (make sure you read the book) and get some rest. Fasting is a great time for the whole person to take a break, let down a bit, do some thinking, journaling, take in the scenery again.
