Hi jamesg~heartburn hurts! Ooh, sorry that happened. Even though you're a vegetarian, you needed to give yourself more than one day to break your cleanse. OJ, watered down a bit to keep the acidity lower, for two days at least would have been a better option, with more watered OJ and a small salad at night on the third day. Have you been taking a probiotic? That also minimizes any other stomach upsets. Good luck, hope this helps.
