>I speak from experience when I say if you want to cure your "sweet tooth" and heal your gut microbiome at the same time, you could try a 3 day water fast.

Excellent move! I start with 1 day water fast and a a good prebiotic supplement. Then a three-day protein only diet. After that, protein and complex carbs for 3 days. Add fruits last. Sosandwich!

It does take will power...by day 2 or 3 of the protein part, you'd kill for a peanut butter sandwhich!

This just cures a sweet tooth. Don't know about your other addictions. I take something for chronic pain but I don't have an addiction to it. (I understand that's not uncommon for people who take a narcotic for chronic pain.)
