You are getting good signs you are near the end of the MC.
Since your tongue is clearing, the Body Odor and breath are much better and you are craving good food, I would not go longer than a week more. I ignored those signs (stubborn) when they happened to me and kept going 2+weeks (Not Smart!).
Yes, you can continue the B&Ps after you start eating, just make sure you don't eat anything 1 hour before or after taking each one.
Some people do them for upto 6 months.
I did them for 6 weeks (while on the MC) and still got ropes out 4 days after stopping the B&Ps. I think they are probably more effective while fasting because your bowels are more clear (no food in the way), but they will still work while eating.
