Flu season - Time to Cleanse

I was just on the phone with a friend who has come down with the flu - I told him that since I started doing the lemonade diet master cleanse once or twice a year I have not had the flu once!

Even a common cold is a rare occurence, I think I've had symptoms once in three years. (I have to admit that an unhealthy diet was probably to blame for that one)

9 days or 10 days?

I recently heard a talk by a doctor and he recommended a 9 day cleanse. In the Stanley Burroughs "Master Cleanse" book he insists on 10 days.

The way I see it is if you can go 9 days you can probably go 10 days. I'd be interested in hearing comments from those who have made it to 10 days.
