I fast once a month for 3 days. I have considered going longer. I just get sick of hearing that I should "eat" from everyone I know. It is very uplifting and I believe the only way to cleanse the body of toxins. All of the food we eat is toxic. Veggies unless you buy the high priced organic, fruit too. Meat unless you buy the high priced free rannge. I can't afford all of this so I fast once a month. Good Luck. I'll keep my fingers crossed for you
