Some good advice have been given. I will agree with the probiotics that are very essential. I started the diet one year ago but from poor diet symptoms came to come back. First day starting drinking acidophilus drink it really made a difference.
I have noticed a lot difference on eating less and more quality food. It certainly make a difference to buy bio stuff, contain so less of that artificial things. Looking every single thing I buy what it contains it certainly makes a difference to me.
Good luck with it.
