I've been doing The Master Cleanse for about 18 years. For the last four years I've been doing it twice a day and it gets easier the more you do it. I'm hoping that's because your body doesn't bulid up so many toxins the more you do it. The first three days are the hardest. It's like stirring up a glass of water with mud at the bottom. Our bodies are the same but it's our toxins that get stirred up instead. That's why the first three days are so hard. The poison has to come out and you may get headaches and irritable etc.
Once you're past the first three days it should be very easy. You must stay focused and remember that it's only for 10 days and think of how great you'll feel when it's all over. You'll lose 1 or 2 pounds a day but most important you'll feel healthy and it will make you want to eat healthy.
I'm a 38 year old female and I believe that thanks to this clease I've stayed very healthy. The only time I used to see a doctor is when I was expecting one of my children. Now, I only go for yearly pap tests.
Be strong and remeber if I can do it...anyone can!
