IF#1 when used as intended, with IF#2 does not cause dependency. It acts to rebuild the muscle and nerve impulses in the intestinal tract so that over time they strengthen and act as they should. Since the damage that has been done to them has occurred over probably lots of years, it can take quite a while to have normal action. I know that Uny and Willowly? have written good posts to this effect before but I couldn't dig them up.
In your case, your need seems so desperate, I wouldn't even worry about dependency until I resolved a few of the more pressing issues! You REALLY need to get things moving and the IF#1 will accomplish that. If I could get some, I would start yesterday, if I were you!!
I am sure you will get lots of help from others but I know that Dr. Schulze always started with colon cleansing for everything!
