Pritikin Recipes

I plan to start the master cleanse Wednesday and I was wondering if I could skip the laxative tea in the morning (I’ve already learned not to do the salt water flush) because I have to be at school at 7am and don’t really want to poop in a school bathroom full of other girls. Or should I wake up around 3, drink the tea and go back to sleep? Will the laxative tea be out of my system before school if I do that? (I’m 18, before anyone thinks I’m too young to do it)
please don’t rant. i don’t care about anyones personal opinion and really only want answers to my question from people who know about/have done the diet.

My question again was about master cleanse and there have been some great answers
