I'll say this, I love me some pizza. Is it an "addiction", perhaps.........it's certainly NOT a disease (this is in response to a comment in the article). Thru sheer willpower, effort I and mental strength I could instantly switch to a healthy diet.
I used to dip a can a day for about 6 years. Plenty enough to have been hooked b/c the headaches and withdraws were definitely present. I quit cold turkey.
Basically.......be mentally tough enough to overcome your brains' reward center.
