About IF#1 being addicting... Dr. Schulze says "it is, if you keep living an unhealthy life." Because, if you keep living an unhealthy life, you'll never get healthy. :-) I know. So simple.
IF #1 gets the sewer unclogged. It's like running the snake down the plumbing pipes. It squeezes your intestines in that peristaltic contraction motion. You want to have about 3 BMs a day as your goal. You take the IF #1 by itself until that happens. If you get too loose, back off.
Then you add IF#2. It's the street sweeper. :-) It comes along and sweeps out all the old gunk you've been holding in for 27 years. You drink the IF #2 5-6 times a day, all throughout the day. Like when you get up, 30 minutes before or after each *raw vegan* meal, and before you go to bed. You mix it up in a glass of fresh juice, chug it down, and follow it with a glass of distilled water. It's so easy. If the IF#2 constipates you a little, you just take another IF#1.
You'll be on these products for a good while. Dr. Schulze himself didn't have a perfectly trained bowel system for years. You will have to be patient, and give your body the tools it needs, like IF#1-2, plus all the other fun things you will be doing, and it will respond with amazing health.
