Master Cleanse- Day 4

I made a decision to end the cleanse. I was unable to drink the lemon drink anymore because it was bothering my teeth, and when I began drinking just plain water, I found myself feeling very tired, lightheaded, and shaky. I also noticed heart palpitations, so I felt that my body was telling me enough. It has been a great experience and one that I will do again in the future under different circumstances. Next time I will do it with fruit and vegetable juice and I'll do it on vacation.
Some thoughts on the Master Cleanse are this. I've begun to question if this is a very healthy process. I don't know how natural it is to consume that much maple syrup and citrus. My other concerns were what the effects of shutting down the intestines and colon are. A big deal is made about using teas or salt water to stimulate the colon, but something about that never felt right. I felt great the first couple of days, but I never drank the recommended amount of the lemonade drink (5-8 glasses). When I started to drink more of the drink my teeth bothered me. When I just drank water I no longer felt good.
I know this cleanse is sometimes referred to as the Lemonade Diet, but I would never recommend it for losing weight because it will mess with your metabolism and the excitement over the weight loss will disappear quickly when the fast is over. I think it is valuable physically to take a break from food, and even more valuable mentally. Any cleansing or fasting routine will automatically reframe how you think of food, and if you want to change your eating habits that is invaluable. For me I felt bad (detox) then great, then very bad. My personal opinion is that I will do short term (3-5 days) juice fasts to renew my body and mind and longer ones (5-15 days) as a spiritual experience.
I think no matter what you do with your body the most important thing of all is that you listen to the messages you receive. Take a break when it's time to break and nourish yourself when it's time to nourish.
