I'm writing for a friend who is fasting for the first time.
On the 3rd morning after the salt water flush, her stomach became so swollen that she looked 6 months pregnant. She felt bloated and she had a bad stomach ache. It stayed liked that all day and she had 3 BMs(all liquid).
Just now, on day four after drinking two lemonade drinks in a row, it happen again.
And to provide more info to help with advice, she has only had Bms 1-2x a week for most of her life.
