Judging from the "best foods to eat" thread, this might be a good place to ask this question. I wanna quit smoking and start eating better. So I'd like some advice on a total system purge. There's so many types and offerings... and snake oil; I don't know where to start or which product actually works. I did some research and some of it even comes back a bit cultish. If it's some hardcore shit, no problem. I can handle it as long as it works, and hopefully, scientifically/medically proven. I'm not getting any younger and I feel sluggish as hell.
