You know, Dr. Fung says if you make it through days 2 and 3, you should easily be able to go 7 days. I have not found that to be true, though. One time I made it to about 4 days and got so freaking hungry, and suddenly, that it was all I could do to make it until 4.5 days.
I’m on day 3, as is my wife. I’m drinking pickle juice at night for the salt, along with taking in salt and potassium, and using magnesium oil. I’m also taking iodine. This might be making me less cold, though last night I slept with a long, heavy shirt on, which is unheard of.
