OP'ing will pull out the toxins that are causing your chronic halitosis.
I used to have halitosis when I first started OP'ing. After 2 months, bad breath went away...and never returned.
I also stopped eating meat and haven't had bad breath since.
What oils are you going to use? Soybean, peanut, corn and canola oils are huge no-no's. Coconut oil may be too strong for a newbie, so start out with sunflower oil (cold-pressed).
