Tanya Zavasta has a great book Quantum Eating where she talks a lot about dry fasting everyday for anywhere from 12 to 18 hours. It is very interesting and informative. The fasting sequence goes a long with the normal night time fasting we do while sleeping and regenerating.
Are you fasting now?
I started last night at 6 pm (2/5/16) trying to start with the new moon this time.
Best of luck with the IF, it has helped me.
